What are five uses for krypton?

Krypton is used commercially as a filling gas for energy-saving fluorescent lights. It is also used in some flash lamps used for high-speed photography. Unlike the lighter gases in its group, it is reactive enough to form some chemical compounds. For example, krypton will react with fluorine to form krypton fluoride.

Why was the element named krypton?

1898: Two British researchers discover the element krypton. Because they had suspected its presence, but had to look for it by removing all that other stuff, Ramsay and Travers gave the element with atomic number 36 the name krypton, from the Greek kryptos for hidden (think cryptography or encryption).

What is the atomic number of krypton gas?

Laboratory Chemical Safety Summary (LCSS) Krypton is a noble gas that is found in the atmosphere. It has the atomic symbol Kr, atomic number 36, atomic weight 83.80, and has been used in electric bulbs. Krypton, compressed, is a colorless, odorless gas.

What happens if you get in contact with krypton?

Krypton (0) is a monoatomic krypton. Krypton, compressed, is a colorless, odorless gas. It is shipped as a liquid under its own vapor pressure. Contact with the liquid may cause frostbite to unprotected skin. It can asphyxiate by displacement of air. Exposure of the container to prolonged heat or fire may cause it to rupture violently and rocket.
