Krypton

element · rare gas · glowing lights

Powers glowing lamps. Krypton gets trapped inside fluorescent and neon-style lights where electricity makes it glow brilliantly. Without gases like krypton, we wouldn't have those cool glowing signs you see in cities.

All around you. Krypton floats invisibly in Earth's atmosphere right now, though in tiny amounts. You're breathing some krypton every single day without ever noticing it.

Super unreactive. Krypton is chemically inert, meaning it almost never reacts with other elements or compounds. It's so stubborn that it basically just floats around doing its own thing.

Totally invisible. Krypton has no color, no smell, and no taste. You could have a whole room full of it and never know unless you saw the glowing light it makes.

Element number 36. Krypton sits at position 36 on the periodic table of elements, making it part of the noble gas family alongside helium and neon.
