You\u2019re probably familiar with the periodic table \u2014 you may have even memorized all the elements. But do you know how they\u2019re used outside of chemistry class?<\/em><\/p><\/blockquote>\n

\"\"<\/a><\/p>\n

Hydrogen (H)<\/strong><\/p>\n

Hydrogen<\/strong> is the most abundant<\/a> element in the universe, and as its atomic number suggests, it\u2019s pretty important. There\u2019s hydrogen in the air you breathe, the water you drink, and the tech on your desk. Gaseous hydrogen is used to manufacture all kinds of electronics (like silicon computer chips). But it could fuel more than laptops soon \u2014 many experts believe hydrogen is the key to clean energy<\/a>.<\/p>\n

Helium (He)<\/strong><\/p>\n

There\u2019s a reason birthday balloons are filled with helium<\/strong>. The noble gas is nonreactive and nontoxic, so it\u2019s unlikely to crash the party. But helium has even cooler applications. With a boiling point of -452 \u00b0F, liquid helium is one of the coldest substances<\/a> in the world. It\u2019s often used to cool down satellite instruments and MRI<\/a> scanners.<\/p>\n

Lithium (Li)<\/strong><\/p>\n

Lithium<\/strong> is the MVP of modern technology. This soft, silvery metal is commonly used to make rechargeable lithium-ion batteries<\/a> for our favorite devices \u2014 cell phones, laptops, digital cameras, and even electric cars. But it\u2019s also used to power the tech we don\u2019t keep on hand all the time. (We\u2019re looking at you, power tools, Roombas, hoverboards, and essentially everything else with a charging port.)<\/p>\n

Beryllium (Be)<\/strong><\/p>\n

As a light, hard metal<\/a> with a sky-high melting point, beryllium<\/strong> is essential in industries that bring the heat. When mixed with other metallic elements, beryllium is used to make springs, gears, cogs, and switches that go inside computers, spaceships, and automobiles. Inception alert: Beryllium alloys are also used to produce the tools<\/a> that manufacture beryllium-based products.<\/p>\n

Boron (B)<\/strong><\/p>\n

It\u2019s a bird, it\u2019s a plane… it\u2019s boron<\/strong>! More often than not, this metalloid can be found in the sky \u2014 it\u2019s used in fireworks and rocket fuel<\/a>. But Boron also has applications at home. Certain compounds are used in laundry detergents and bleaches, as well as mild antiseptics<\/a>. In the electronics industry, some boron oxides are used to make heat-resistant glass<\/a>.<\/p>\n

Carbon (C)<\/strong><\/p>\n

Carbon<\/strong> is the building block of all life. It can form both graphite<\/a> (one of the softest materials on earth) and diamond<\/a> (the world\u2019s hardest substance). It\u2019s used in everyday objects, like black printer ink, but it\u2019s also found in plant and animal cells<\/a>. Some<\/a> compounds are deadly, but others<\/a> are essential components of the air we breathe.<\/p>\n

Nitrogen (N)<\/strong><\/p>\n

If you want to get up close and personal with nitrogen<\/strong>, all you have to do is breathe. This omnipresent element makes up approximately 78%<\/a> of air on Earth! When electronics manufacturers build tech, they use nitrogen gas<\/a> to create an inert (or nonreactive) atmosphere. This prevents<\/a> unwanted chemical reactions like oxidation<\/a> during the manufacturing process.<\/p>\n

Oxygen (O)<\/strong><\/p>\n

Element #8 is one of the most important gases on earth \u2014 and in the atmosphere. Without the protective ozone layer<\/a> (which contains oxygen<\/strong>), we’d be exposed to a dangerous amount of ultraviolet radiation<\/a>. Pure oxygen is most widely used<\/a> in steel manufacturing. In some factories, it’s blown directly into molten iron to remove impurities.<\/p>\n

Fluorine (F)<\/strong><\/p>\n

Been to the dentist lately? You probably heard a lot about flossing and fluoride. Sodium fluoride is a fluorine compound that\u2019s added to toothpaste and drinking water to prevent cavities<\/a>. But fluorine can clean more than just teeth. In manufacturing, this element is used to refine metals and polish glass<\/a>.<\/p>\n

Neon (Ne)<\/strong><\/p>\n

Neon<\/strong> can take credit for vibrant signs lining the Las Vegas strip. (Fun fact: only red<\/a> ssigns contain pure neon \u2014 you need a mixture of other gases to get the rest of the rainbow.) But, neon is also used in tech production. You can find the gaseous element<\/a> in TV tubes, power lines and (wait for it) lasers.<\/p>\n

Sodium (Na)<\/strong><\/p>\n

Sodium<\/strong>. It\u2019s a dinner table essential and the punchline of every Batman-themed chemistry joke. Aside from its undisputed role in the culinary world, sodium salts are used to manufacture artificial rubber compounds<\/a>. Conductive rubber<\/a> coverings are often used in the telco industry to protect wires from electromagnetic interference. This reduces noise in TVs, radios, and audio speakers alike.<\/p>\n

Magnesium (Mg)<\/strong><\/p>\n

Since magnesium<\/strong> is lightweight and malleable<\/a>, it\u2019s used in small portable electronics like phones, laptops, and cameras. Due to increased demand for efficient tech products, magnesium alloys are even replacing plastics<\/a> \u2014 these alloys weigh about the same but are much more durable. Plus, they\u2019re resistant to electromagnetic interference.<\/p>\n

Aluminum (Al)<\/strong><\/p>\n

Aluminum<\/strong> is a soft, lightweight<\/a> metal that can be found in everything from telescope mirrors<\/a> to airplane parts and electrical transmission lines. This conductive element<\/a> even has uses in nanoparticle technology. Aluminum is cheap and nontoxic, so when it\u2019s not being used in subatomic science, it\u2019s a major player in the packaging industry.<\/p>\n

Silicon (Si)<\/strong><\/p>\n

Silicon<\/strong> is an extremely useful element because it\u2019s an ideal semiconductor<\/a>. That means it has an intermediate conductivity \u2014 it\u2019s not extremely conductive, but it doesn\u2019t stop the flow of electricity, either. Silicon is most commonly used in computer chips, LCDs, and solar cells<\/a>. Lower quality silicon is often mixed with other metals<\/a> to create steel, brass, and bronze.<\/p>\n

Phosphorus (P)<\/strong><\/p>\n

Steel is a major technology metal<\/a> \u2014 and we likely wouldn\u2019t have as many steel-based electronics or wires without phosphorus<\/strong>. Phosphorus plays an important role<\/a> in steel production: it increases tensile strength<\/a> and reduces vulnerability to corrosion<\/a>. This makes the steel used in our tech a lot more durable, so you can drop your new iPhone 8<\/a> without major structural damage.<\/p>\n

Sulfur (S)<\/strong><\/p>\n

If you want to find sulfur<\/strong>, you\u2019ve got to go exploring. The characteristically yellow element is found near volcanoes<\/a> and in deposits deep underground. About 90%<\/a> oof all sulfur consumed by the U.S. is converted into sulfuric acid<\/a>. This compound is a key ingredient in the fertilizer that helps grow crops across the country.<\/p>\n

Chlorine (Cl)<\/strong><\/p>\n

This familiar element can kill bacteria<\/a>, so it\u2019s used to keep pools clean. But swimmers beware: liquid chlorine can cause chemical burns in high concentrations. In industry, certain forms of chlorine are used to manufacture silicon<\/a>, rubber, electrical wiring, and plastic. So, the chemical plays an understated \u2014 yet important \u2014 role in creating computer chips, TVs, and cell phones.<\/p>\n

Argon (Ar)<\/strong><\/p>\n

This colorless, odorless noble gas is best-known for being non-reactive. In fact, argon<\/strong> got its name<\/a> from argos<\/em>, the Greek word for \u201clazy.\u201d The element is commonly used to fill incandescent light bulbs and fluorescent tubes. Manufacturers choose argon instead of normal air because oxygen corrodes<\/a> the metal filaments inside. Argon increases a light bulb\u2019s lifespan, simply by doing nothing.<\/p>\n

Potassium (K)<\/strong><\/p>\n

Pure potassium<\/strong> is super explosive, so it\u2019s rarely<\/a> found free in nature. (Don\u2019t worry \u2014 the healthy stuff in bananas is a potassium compound.) Liquid potassium is often used to regulate temperatures in nuclear power plants<\/a> by transferring heat from the core reactor toward steam-powered electric generators.<\/p>\n

Calcium (Ca)<\/strong><\/p>\n

As the fifth-most-abundant element<\/a> in the Earth\u2019s crust and the main component<\/a> of our bones, calcium<\/strong> is a biology superstar. In the tech space, though, this element steps back to let other metals shine. It\u2019s mostly used to remove impurities from iron ore and to produce metal alloys. Calcium with the assist!<\/p>\n

Scandium (Sc)<\/strong><\/p>\n

This element may be low-density, but it\u2019s high intensity. Scandium<\/strong> is super strong, making it a great fit for the aerospace industry. Since it can withstand extreme conditions without cracking<\/a> or melting, scandium is commonly used to construct airplanes. It\u2019s particularly important on exterior parts, like the fuselage<\/a>. Now there\u2019s a five-dollar word.<\/p>\n

Titanium (Ti)<\/strong><\/p>\n

Titanium<\/strong> is a renaissance metal<\/a> of sorts. It\u2019s as strong as steel but nearly twice as light<\/a> \u2014 and its corrosion resistant. At the turn of the century, Apple<\/a> released a line of laptops featuring a titanium body<\/a>. Though the PowerBook G4 was well received, aluminum<\/a> has proven to be more practical. These days, titanium is primarily used<\/a> for surgical applications and aerospace construction.<\/p>\n

Vanadium (V)<\/strong><\/p>\n

Most of the world\u2019s vanadium<\/strong> is added to steel to make stronger alloys. But a little goes a long way. Even a tiny amount<\/a> of vanadium is enough to make steel shock and vibration resistant<\/a>. Once metals are mixed with element #23, they\u2019re ready to endure a variety of volatile environments, from nuclear reactors to combustion engines.<\/p>\n

Chromium (Cr)<\/strong><\/p>\n

In industry, chromium<\/strong> is used to create rust-resistant stainless steel<\/a>. But chromium also has virtual applications \u2014 it\u2019s the namesake of the world\u2019s most popular<\/a> web browser. Google Chrome<\/a> owes its newfound fame to the Chromium Project<\/a>, an initiative that ensured everyone\u2019s favorite internet application would be fast, safe, reliable, and accessible.<\/p>\n

Manganese (Mg)<\/strong><\/p>\n

Manganese<\/strong> is mainly used in steel production<\/a> to remove impurities from iron ore. But this element also plays an underrated role in many of our favorite devices. Manganese ferrites<\/a> (or, fancy magnets) are used in all kinds of electronics<\/a>, from circuit boards to cable cords. These magnets suppress certain frequencies and reduce interference so that your screens are static-free.<\/p>\n

Iron (Fe)<\/strong><\/p>\n

Iron<\/strong> is abundant and inexpensive<\/a>, giving it some serious popularity points. In fact, it\u2019s the most widely used metal<\/a> on the periodic table \u2014 90%<\/a> of all refined metal is iron. It has countless applications and can be found in everything from automobiles to electronics. Although iron is highly corrosive<\/a>, it\u2019s often alloyed to make more durable metals.<\/p>\n

Cobalt (Co)<\/strong><\/p>\n

Silvery-blue<\/a> cobalt<\/strong> is used to make batteries for rechargeable electronics. Since cobalt improves conductivity, it\u2019s a popular addition to nickel and lithium alloys. With more efficient alloys, manufacturers are able to craft lighter batteries with less environmental impact<\/a>. Experts predict<\/a> that the element will see all new applications with the rise of electric vehicles.<\/p>\n

Nickel (Ni)<\/strong><\/p>\n

You guessed it. Nickel<\/strong> is the stuff inside our 5-cent piece. It\u2019s mainly used to make small batteries<\/a> for smartphones and laptops. But it also has a less typical tech application: nickel alloys are used in desalination plants<\/a>, which convert salt water into drinkable water. What\u2019s the secret to being a desalination star? Corrosion resistance<\/a>, even in stormy seas.<\/p>\n

Copper (Cu)<\/strong><\/p>\n

Copper<\/strong> was one of the first metals<\/a> ever used by humans. Hundreds of years ago, our ancestors shaped the malleable material into coins. Turns out, they got it right \u2014 today, all U.S. coins<\/a> are copper alloys. Copper has applications in just about every industry, but it\u2019s especially well-suited for electronics. You can thank copper-based coaxial cables for delivering internet and cable TV service.<\/p>\n

Zinc (Zn)<\/strong><\/p>\n

About half<\/a> of all zinc<\/strong> consumed by the U.S. is used to galvanize other metals. With a coat of molten zinc, rust-prone elements are much more resistant to corrosion. Fun fact: galvanized steel is used to construct gigantic structures, like the Golden Gate Bridge<\/a>. But zinc is more than an additive. Its compounds are used to manufacture all kinds of products<\/a>, from paint to batteries.<\/p>\n

Gallium (Ga)<\/strong><\/p>\n

Gallium<\/strong> is a pretty great stunt double. This element has a similar structure<\/a> to silicon, so it\u2019s widely used in the electronics industry. You can find gallium in LED lights, cell phones, computers, and TVs. It\u2019s also a great substitute for toxic mercury. Since gallium melts around room temperature<\/a>, it\u2019s commonly found in medical thermometers.<\/p>\n

Germanium (Ge)<\/strong><\/p>\n

Like many semiconductors, germanium<\/strong> is used to manufacture alloys. However, it\u2019s relatively rare, so it\u2019s not in the mix as often as other members of its metalloid family. Most germanium is used to manufacture glass for fiber optics<\/a> and optical lenses. Since germanium gives glass a high index of refraction<\/a>, it\u2019s used to create special lenses for wide-angle cameras and microscopes.<\/p>\n

Arsenic (As)<\/strong><\/p>\n

Do you feel nervous at the mention of arsenic<\/strong>? Many people do. It\u2019s a common ingredient in pesticides, and it\u2019s been used to poison people, too. (Yikes.) In the tech world, arsenic has a much less sinister purpose<\/a>: it\u2019s often used to dope silicon in a semiconductor<\/a>. This allows the silicon to conduct electricity more easily \u2014 and makes it more attractive for use in solid-state<\/a> devices.<\/p>\n

Selenium (Se)<\/strong><\/p>\n

Though it\u2019s hard to come by, selenium<\/strong> can be used to manufacture glass and electronic equipment. The solar industry owes a lot to selenium \u2014 it was a key ingredient in the first photovoltaic cell<\/a>. However, it\u2019s not all sunshine and roses: selenium compounds are toxic. In fact, plants grown in soil that contains selenium may become poisonous<\/a>.<\/p>\n

Bromine (Br)<\/strong><\/p>\n

Bromine<\/strong> is commonly used as a flame retardant in plastics \u2014 particularly in circuit boards and wire casings. These additives are used to prevent electrical fires. However, research<\/a> suggests that these chemicals are toxic. Lately, there\u2019s been much debate<\/a> over whether handheld electronics even need to be fire-proofed. Apple<\/a> weighed in by replacing BRF<\/a>s with safer alternatives<\/a>.<\/p>\n

Krypton (Kr)<\/strong><\/p>\n

Krypton<\/strong> doesn\u2019t just spell trouble for Superman. Even outside the city of Metropolis, some isotopes of krypton are radioactive<\/a>. Safer compounds of the clear gas are often combined with xenon to produce energy-saving<\/a> light bulbs. These krypton-filled bulbs produce brighter light<\/a> and last longer than their halogen-filled counterparts.<\/p>\n

Rubidium (Rb)<\/strong><\/p>\n

Though rubidium<\/strong> is usually restricted to the confines of a research lab, it has been used to manufacture photoelectric cells<\/a>. Generally, a photocell<\/a> is any device that uses light to generate an electric current. These cells can power a variety of electronics<\/a> including alarm systems, automatic door openers, and solar batteries.<\/p>\n

Strontium (Sr)<\/strong><\/p>\n

Certain isotopes of strontium<\/strong> are too dangerous to touch \u2014 Strontium-90<\/a> gives off enough beta radiation to generate electricity for space vehicles<\/a>. But, in safer forms, the element can be used to produce the Cathode Ray Tubes (CRTs) used in old-school TV screens and computer monitors. Talk about an element that can do both.<\/p>\n

Yttrium (Y)<\/strong><\/p>\n

Need a durability boost? Just add yttrium<\/strong>. Yttrium oxides are used to strengthen metal alloys and to make glass heat and shock resistant<\/a>. This is great news for professional photographers, selfie enthusiasts, and everyday smartphone users who rely on clear, durable camera lenses.<\/p>\n

Zirconium (Zr)<\/strong><\/p>\n

If this name sounds familiar, you\u2019re probably thinking of cubic zirconia<\/a>, a zirconium oxide that crystallizes as a diamond-like synthetic gemstone. Tech-wise, zirconium<\/strong> is primarily<\/a> used in nuclear power stations since it\u2019s resistant to both chemical corrosion and heat. This metal works particularly well in nuclear fuel rods<\/a> to help facilitate reactions.<\/p>\n

Niobium (Nb)<\/strong><\/p>\n

Niobium<\/strong> alloys are super strong, so it\u2019s no surprise that they\u2019re found in jet engines<\/a>. The element is primarily used to strengthen other metals, and its ability to work well with others gives it a wide range of applications. For example, niobium-titanium alloys<\/a> are used to build MRI magnets. This just proves that sometimes two elements are better than one.<\/p>\n

Molybdenum (Mo)<\/strong><\/p>\n

No movie night is complete without molybdenum<\/strong> \u2014 the shiny metal is a key ingredient in manufacturing LCD<\/a> screens. Compared to more outdated cathode-ray tubes, LCD technology offers dramatically improved picture quality. And since LCDs are less bulky than CRTs, they\u2019re often used in modern flat screen TVs, tablets, computers, and smartphones.<\/p>\n

Technetium (Tc)<\/strong><\/p>\n

Technetium<\/strong> was the first element to be produced synthetically<\/a>. This artificial metal has never been found on earth (though it has been seen in stars<\/a>). For now, we\u2019re happy to keep technetium light years away \u2014 the radioactive<\/a> element is toxic. Technetium can be added to steel to protect it from corrosion. However, this alloy has limited uses<\/a> since direct exposure is so dangerous.<\/p>\n

Ruthenium (Ru)<\/strong><\/p>\n

When mixed with other metals, ruthenium<\/strong> is used to manufacture chip resistors<\/a>. Chip resistors help regulate electrical currents in compact circuit boards<\/a>. They can be used to either maintain the electrical current or drop the voltage down lower. Engineers are working to develop more efficient resistors so that they can be used in our smallest handheld devices.<\/p>\n

Rhodium (Rh)<\/strong><\/p>\n

Rhodium<\/strong> is primarily used in to create catalytic converters<\/a> for cars, trucks, and other automobiles. (No, they\u2019re not limited to Cadillacs.) Though catalytic converters aren\u2019t as exciting as rims or spoilers, they\u2019re a critical component of every car. These devices control vehicle emissions by converting toxic gas exhaust into less harmful pollutants.<\/p>\n

Palladium (Pd)<\/strong><\/p>\n

Palladium<\/strong> is commonly used in the electronics industry to make ceramic capacitors<\/a> for laptops and cell phones. In this type of capacitor, palladium sheets are insulated by ceramic layers. These versatile devices can be produced in a variety of sizes and voltages<\/a>, so they\u2019re found in everything from circuit boards to robots.<\/p>\n

Silver (Ag)<\/strong><\/p>\n

As the most conductive metal<\/a> on the periodic table, it\u2019s no surprise that silver<\/strong> is expensive. Though it was historically used in jewelry, coins, and luxury items, silver is now primarily<\/a> used in electronic tech. The shiny metal can be found in tracking devices, solar panels, LED lights, and TVs. If it has an on\/off switch, chances are it contains silver.<\/p>\n

Cadmium (Cd)<\/strong><\/p>\n

The vast majority<\/a> of cadmium<\/strong> is used to produce rechargeable batteries. The element\u2019s low melting point<\/a> makes it a valuable ingredient in solder alloys<\/a> as well. Solder alloys are designed to seal two metals together \u2014 usually electrical components or pipes. Unfortunately, cadmium is a known carcinogen<\/a>. Since direct exposure is dangerous, many organizations have eliminated its use.<\/p>\n

Indium (In)<\/strong><\/p>\n

Indium<\/strong> is a soft silvery metal named after the indigo-colored line in its spectrum<\/a>. It\u2019s often used to produce indium tin oxide<\/a> (ITO), a key ingredient in touch screens. Touch screens need a conductive material like indium, which can detect changes in its electric field. (Yep, your fingers hold an electric charge.)<\/p>\n

Tin (Sn)<\/strong><\/p>\n

Humans have mined and used tin<\/strong> for thousands of years<\/a>. Our ancestors mixed tin and copper to create bronze<\/a>, which they then used to craft statues, weapons and tools, jewelry, coins, and more. (Want a mini history lesson? See also: the Bronze Age<\/a>.) Today, we use tin to create powerful magnets<\/a> and superconductive wire<\/a>.<\/p>\n

Antimony (Sb)<\/strong><\/p>\n

Antimony<\/strong> is a poor conductor<\/a> of electricity, but still has an important role in many of the electronics we use. The semi-metal is used to manufacture batteries, diodes, and cable sheathing, which can make devices more efficient. It can also be added to compounds in order to make them fire-resistant. Thinking of making a superhero suit? Antimony might not be a bad addition.<\/p>\n

Tellurium (Te)<\/strong><\/p>\n

Small amounts<\/a> of tellurium<\/strong> can make big improvements to metal alloys. For example, just a little tellurium increases tin\u2019s hardness and makes copper and stainless steel easier to work with<\/a>. Tellurium compounds can be used to manufacture thermoelectric devices<\/a>, but these power generators aren\u2019t quite as efficient as their competitors<\/a>.<\/p>\n

Iodine (I)<\/strong><\/p>\n

Seaweed isn\u2019t just for sushi anymore. Kelp can be dried, burned<\/a> and processed to create iodine<\/strong>. For decades, this element has been used to produce photography<\/a> film. But more recently, iodine is used to manufacture LCDs for smartphones and HD TVs. It\u2019s used to make polarizing films<\/a>, which increase the visibility of images on your screen.<\/p>\n

Xenon (Xe)<\/strong><\/p>\n

Like many other noble gasses, xenon<\/strong> is widely used in lighting. It\u2019s built a reputation as the best and brightest<\/a> when it comes to camera flash technology. However, you\u2019re probably not carrying one around in your pocket. Most smartphone cameras rely on LED lights because they\u2019re smaller and cheaper<\/a> than xenon flashes. That hasn\u2019t stopped companies like Fotopro<\/a> from trying, though.<\/p>\n

Cesium (Cs)<\/strong><\/p>\n

Late to class? Blame cesium<\/strong>. This golden metal fuels the world\u2019s most accurate atomic clock. Using microwave emissions from cesium atoms, the clock (affectionately named NIST-F2<\/a>) defines the exact length of a second and sets the standard for all other timepieces. It\u2019s used to synchronize time<\/a> across cell phone networks, power grids, GPS satellites, and the internet.<\/p>\n

Barium (Ba)<\/strong><\/p>\n

Barium<\/strong> compounds are toxic<\/a>, so they aren\u2019t as popular as many other alloys. However, this dense metal can be used to manufacture glass<\/a>. Even if you can\u2019t see it, glass is a fundamental component in all kinds of technology. The material has applications in virtually every industry<\/a> \u2014 from solar energy panels and TV screens to medical devices and fiber-optic cables.<\/p>\n

Lanthanum (La)<\/strong><\/p>\n

Lanthanum<\/strong> is so soft that it can be cut with a knife<\/a>, so the metal is not particularly useful on its own. However, its alloys are. Car companies like Toyota and Nissan<\/a> use lanthanum to make rechargeable batteries for their hybrid cars. Beyond the auto industry, the U.S. military uses lanthanum to produce defense technology, like night vision goggles<\/a>.<\/p>\n

Cerium (Ce)<\/strong><\/p>\n

Be careful around pure cerium<\/strong> \u2014 it\u2019ll spark if it comes in contact with another sharp object. That\u2019s why it\u2019s widely used in lighter flints<\/a>. Cerium is much tamer when combined with other metals, so its alloys are used in a variety of electronics, from low energy light bulbs to flat screen TVs. Some cerium compounds<\/a> can also help produce, polish, and remove color from glass.<\/p>\n

Praseodymium (Pr)<\/strong><\/p>\n

Praseodymium<\/strong> is a silver, moderately toxic<\/a> element that\u2019s used to manufacture high-intensity magnets. These magnets are an important power source in green electronics, like hybrid car engines and wind turbines. But this rare earth metal has both brawn and beauty. Its compounds produce yellow glass and synthetic green gemstones<\/a>.<\/p>\n

Neodymium (Nd)<\/strong><\/p>\n

This element is primarily used to create super-strong permanent magnets<\/a>. These magnets can be found in all kinds of electronics, from computer hard drives to motors. Neodymium<\/strong> can also add special properties to glass. It can be used to make fiber optic cables<\/a> (which transmit high-quality TV and internet service) or to block harmful light rays in welding goggles<\/a>.<\/p>\n

Promethium (Pm)<\/strong><\/p>\n

Promethium<\/strong> is a radioactive metal with no stable isotopes, so don\u2019t get too close. Though most promethium is reserved for research<\/a>, it can be a source of energy in small electronics that need a dependable power source, like pacemakers. Scientists believe that promethium\u2019s radioactive decay could be converted into electricity<\/a> to power nuclear batteries.<\/p>\n

Samarium (Sm)<\/strong><\/p>\n

Hard, heat-resistant cobalt is the perfect partner in crime for a soft silvery metal like samarium<\/strong>. Together, these elements make strong magnets<\/a>. Samarium can also be used to produce the cathode ray tubes inside old-school computer displays and TV screens. CRT monitor sales peaked<\/a> at the turn of the century, but have rapidly declined to make way for higher quality LCD<\/a> technology.<\/p>\n

Europium (Eu)<\/strong><\/p>\n

Europium<\/strong> is a soft, reactive metal with a propensity for spontaneous combustion<\/a> when it gets too hot. These properties make it a great nuclear fuel source. But europium\u2019s radioactivity makes it useful even beyond the power industry. Fun fact: europium compounds are added to Euro banknotes<\/a> as anti-counterfeit measures. On genuine notes, the europium glows red<\/a> under UV light.<\/p>\n

Gadolinium (Gd)<\/strong><\/p>\n

This element plays a minor (but important) role in all kinds of places. In the electronics industry, gadolinium<\/strong> can be found in CDs and computer memory. In manufacturing, the magnetic element is added to alloys to make hard metals more workable<\/a>. Most importantly, gadolinium is used in the medical field to enhance MRI images<\/a>. This helps doctors accurately detect cancerous tumors.<\/p>\n

Terbium (Tb)<\/strong><\/p>\n

This little-known element can be found in all kinds of technologies<\/a>, from fiber optics to smartphone screens. However, terbium<\/strong> is primarily used to stabilize fuel cells<\/a> and manufacture phosphors. A phosphor<\/a> is a solid material that can emit light when exposed to radiation. Terbium phosphors typically give off a green light \u2014 you\u2019ll find them in TVs and computer monitors.<\/p>\n

Dysprosium (Dy)<\/strong><\/p>\n

Like many other lanthanides<\/a>, dysprosium<\/strong> is too temperamental to have widespread applications on its own. But, that changes when it\u2019s combined with other elements. A special dysprosium-based cement<\/a> is used to safely cool nuclear reactor rods. And when dysprosium is combined with other rare earth metals, it can be used to make laser materials<\/a>.<\/p>\n

Holmium (Ho)<\/strong><\/p>\n

Recent research has turned up some exciting applications for holmium<\/strong>. According to IBM, the average hard drive uses up to 10,000 atoms<\/a> to store one bit of data. However, researchers have proven that it\u2019s possible to store data on a single atom<\/a>. Using holmium\u2019s magnetic field, IBM<\/a> scientists invented the world\u2019s smallest magnet. For now, it\u2019s just a prototype, but it holds huge promise.<\/p>\n

Erbium (Er)<\/strong><\/p>\n

Love super-speedy internet? We owe it to erbium<\/strong>. This rare-earth element emits light at wavelengths commonly used in fiber-optic<\/a> signal transmission. So, erbium is most commonly<\/a> used to produce signal amplifiers for long-distance fiber-optic cables. Fiber-optic technology is popular because it uses light (not electricity) to transmit lots of data, faster than aging coaxial cable networks.<\/p>\n

Thulium (Tm)<\/strong><\/p>\n

Thulium<\/strong> can be combined with durable yttrium to create high-temperature superconductors<\/a>. And though the element is slightly toxic, certain isotopes can be used in x-ray equipment<\/a>. There’s just one issue: thulium costs a pretty penny. The expensive<\/a> metal is also being considered as a potential energy source, but for now, it has little practical use beyond research.<\/p>\n

Ytterbium (Yb)<\/strong><\/p>\n

Ytterbium<\/strong> is a relatively rare, volatile metal<\/a>. It can be used in portable X-ray devices and as a dopant in a variety of materials. Dopants<\/a> are intentionally added to semiconductors in order to alter their electrical properties. In this case, ytterbium-doped glasses have a simple electronic structure<\/a> and are well-suited for fiber-optic cables.<\/p>\n

Lutetium (Lu)<\/strong><\/p>\n

Lutetium<\/strong> is the last of the lanthanide metals. It\u2019s high-melting and incredibly dense, but it isn\u2019t very useful in industry. Lutetium-176 can help us determine the age of meteorites<\/a>. However, outside of astronomy, there aren\u2019t many uses for lutetium. For now, we\u2019ll keep this silvery metal locked in the research lab \u2014 especially since we aren\u2019t sure<\/a> just how toxic it is.<\/p>\n

Hafnium (Hf)<\/strong><\/p>\n

Hafnium<\/strong> is so similar to zirconium<\/a> that it\u2019s often difficult for scientists to tell them apart. Like its identical twin element, hafnium is useful in the nuclear power industry. But it\u2019s more commonly used as an electrical insulator<\/a> in microchips. By ensuring that these chips conserve energy and run more efficiently, hafnium helps us make smaller microchips for portable electronic devices.<\/p>\n

Tantalum (Ta)<\/strong><\/p>\n

About half<\/a> of all tantalum<\/strong> is consumed by the electronics industry. The silvery metal is resistant to corrosion<\/a>, so it creates efficient capacitors for mobile phones, laptops, and gaming consoles. (Capacitors<\/a> are the magical devices that keep your electronics charged.) Since tantalum oxides are insulating, they\u2019re also used to coat other metals.<\/p>\n

Tungsten (W)<\/strong><\/p>\n

There\u2019s no other way to say it, tungsten<\/strong> is tough. The super-dense element is almost impossible to melt \u2014 in fact, it has the highest melting point<\/a> of all metals. As you might guess, tungsten is important for jobs like welding and metal-working. But you can also find tungsten in your everyday electronic devices. Since it can withstand erosion<\/a>, tungsten is commonly used to make electrical circuits.<\/p>\n

Rhenium (Re)<\/strong><\/p>\n

Rhenium<\/strong> is one of the rarest metals<\/a> around. When it is found, it\u2019s usually combined with tungsten to create an extremely heat-resistant alloy. Rhenium\u2019s durability makes it useful in x-ray machines<\/a>, where it\u2019s constantly exposed to radiation. But, the material is also great at passing electrical currents from one conductor to another. Which devices need electrical conductors? Only all of them.<\/p>\n

Osmium (Os)<\/strong><\/p>\n

Due to its high density<\/a>, osmium<\/strong> is a great material for making electrical contacts. Electrical contacts are the building blocks of modern electronics \u2014 they help electricity flow through devices<\/a>. A good contact reduces friction and helps ensure that electricity moves efficiently. Since osmium is conductive and strong enough to carry high voltage currents, it’s the perfect element for the job.<\/p>\n

Iridium (Ir)<\/strong><\/p>\n

The most corrosion-resistant metal<\/a> on earth is actually an element from outer space. Scientists believe that iridium<\/strong> was scattered across the globe when a giant meteor<\/a> collided with earth millions of years ago. Despite its alien origins, iridium is a highly-coveted alloying agent. The hard, durable, heat-resistant metal is often used to produce spark plugs<\/a>.<\/p>\n

Platinum (Pt)<\/strong><\/p>\n

They don\u2019t call it “going platinum<\/strong>” for nothing. In terms of tech, this element is one of the best. Platinum is a great conductor of electricity, so it\u2019s used to make fiber optics, LCD displays, and even pacemakers. The precious metal is also adored by the auto industry. About half<\/a> of all platinum is used in catalytic converters, which clean up car emissions and improve fuel efficiency.<\/p>\n

Gold (Au)<\/strong><\/p>\n

Watches. Teeth. Olympic medals. Gold<\/strong> can be used to make just about anything<\/a>. The rare yellow metal is an excellent conductor of electricity, so it\u2019s a key ingredient in high-end electronics. Despite its industrial utility, gold is most popular for its looks alone \u2014 about 78%<\/a> of gold is used to manufacture jewelry.<\/p>\n

Mercury (Hg)<\/strong><\/p>\n

Mercury<\/strong> is the only metal<\/a> that\u2019s liquid in its natural phase. But it\u2019s better to admire at a distance \u2014 mercury is toxic in high doses. For centuries, it was used in common household items<\/a> like batteries, fluorescent lights, and thermometers. In order to reduce the risk of mercury poisoning, the World Health Organization<\/a> has taken action to phase out<\/a> non-essential mercury products.<\/p>\n

Thallium (Tl)<\/strong><\/p>\n

Thallium<\/strong> is so dangerous that it was historically used as rat poison. But rodents can relax \u2014 in recent years, thallium-based poisons have been banned<\/a> in the United States. The electronics industry uses thallium sulfide (a mixture of thallium and sulfur) to produce photoelectric cells. These cells are particularly unique because their conductivity increases<\/a> when exposed to certain types of light<\/a>.<\/p>\n

Lead (Pb)<\/strong><\/p>\n

Commercial use of lead<\/strong> in paint and other household products has become less common since we figured out what lead poisoning<\/a> is. (Makes sense.) Lead is still often found<\/a> in car batteries and electrical cable sheathing, so those who frequently come in contact with those objects \u2014 like mechanics or construction workers \u2014 take special precautions to avoid exposure.<\/p>\n

Bismuth (Bi)<\/strong><\/p>\n

This metal is a fire station favorite. Though it\u2019s too brittle to be used on its own, bismuth<\/strong> is often mixed with other elements to make alloys. When bismuth is alloyed, the finished product picks up some of the metallic element\u2019s best properties, like its low melting point<\/a>. Since these alloys can withstand high heats, they\u2019re often used<\/a> in smoke detectors and fire extinguishers.<\/p>\n

Polonium (Po)<\/strong><\/p>\n

Polonium<\/strong> is rare and highly radioactive. Though it can be used as a heat source<\/a> for space equipment, its half-life is too short to generate long-term energy \u2014 some polonium isotopes have a half-life of less than a second<\/a>. Polonium does have a unique purpose: it helps reduce static. Today it\u2019s mostly used to eliminate static in manufacturing processes for paper, plastic, and metal.<\/p>\n

Radon (Rn)<\/strong><\/p>\n

Radon<\/strong> exists naturally in the earth\u2019s soil, but it can be extremely dangerous. As radon decays, it produces other radioactive isotopes like polonium and lead<\/a>. Exposure to radon (and its daughter<\/a> elements) has been linked to lung cancer<\/a>. It was once used to target cancerous cells via radiation therapy. However, today doctors use more efficient isotopes<\/a> to treat cancer.<\/p>\n

Thorium (Th)<\/strong><\/p>\n

That’s right, this metal was named after the hammer-toting mythological god, Thor<\/a>. Though thorium<\/strong> compounds can produce camera lenses and solar panels, it\u2019s found in nuclear reactor fuel<\/a>. It\u2019s predicted that the thorium metal in the earth\u2019s crust could produce more fuel than both uranium and fossil fuels<\/a>.<\/p>\n

Uranium (U)<\/strong><\/p>\n

Radioactive uranium<\/strong> is a well-known fuel source for nuclear power plants<\/a>. This reactive metal releases energy when its atoms split during a process called nuclear fission<\/a>. Just one pound of uranium produces as much fuel as 1500 tons of coal<\/a>. Accidental exposure to materials like uranium could have deadly consequences for humans, animals, and the environment.<\/p>\n

Plutonium (Pu)<\/strong><\/p>\n

Plutonium<\/strong> is named after Pluto. This radioactive element has extraterrestrial applications \u2014 it\u2019s used to generate electricity<\/a> for space vehicles that travel so far from the sun that they can\u2019t use solar power. Due to its explosive properties<\/a>, it was used in the first atomic bomb and is still used in nuclear weapons.<\/p>\n

Americium (Am)<\/strong><\/p>\n

Though this radioactive element is toxic, it can help save lives. Americium<\/strong> is a key ingredient in smoke detectors<\/a>. The element emits a constant stream of alpha particles<\/a>, and if smoke interrupts the flow, it triggers the alarm. Americium ionization detectors react<\/a> to the tiny smoke particles produced by fast-burning fires faster than photoelectric alarms can.<\/p>\n

Curium (Cm)<\/strong><\/p>\n

Curium<\/strong> is mainly used<\/a> for scientific research. However, the transuranium element has some interesting properties. Just one gram of curium produces three watts of thermal energy<\/a>, outpacing radioactive plutonium. Curium can be used to generate energy for space vehicles. In fact, a curium battery was used to fuel instruments on the Mars Pathfinder mission<\/a>.<\/p>\n

Californium (Cf)<\/strong><\/p>\n

Californium<\/strong> is a completely synthetic element that does not exist in nature. The radioactive metal was discovered by chemists<\/a> at the University of California Berkeley, and it’s named after the Golden Bears’ home state. For now, engineers are working on timed neutron detectors<\/a>, which use californium isotopes to detect landmines.<\/p>\n
