Please Register or Log in to view the hidden image! Thanks to high school, we’ve all got a pretty good idea about what’s on the periodic table. But whether you’re looking at something common like calcium, iron, and carbon, or something more obscure like krypton and antimony, how well do you know their functions? Could you name just one practical application for vanadium or ruthenium? Lucky for us, Keith Enevoldsen from elements.wlonk.com has come up with this awesome periodic table that gives you at least one example for every single element (except for those weird superheavy elements that don’t actually exist in nature). There’s thulium for laser eye surgery, cerium for lighter flints, and krypton for flashlights. You’ve got strontium for fireworks, and xenon for high-intensity lamps inside lighthouses. Oh and that very patriotic element, americium? We use that in smoke detectors. First unveiled in 1945 during the Manhattan Project, americium is produced by bombarding plutonium with neutrons in a nuclear reactor. The resulting americium is radioactive, and while the tiny amounts of americium dioxide (AmO2) used in smoke detector produces alpha radiation to sniff out a fire, it will deliver approximately zero radiation to anyone living nearby. I kinda want to tell you all about rubidium and how we use it in the world’s most accurate time-keeping devices, and how niobium can help make trains levitate, but you should just check out the periodic table for yourself.
