Term: krypton (Kr)
Literally meaning: “hidden”
Origin: Anc Greek
The element was discovered in 1898 by Scottish chemist (sir) William Ramsey (1852-1916) and his assistant English chemist Morris Travers (1872-1961). The two scientists managed to isolate krypton after boiling away water oxygen, nitrogen, helium and argon from liquefied air.
Crypton is a chemical element with atomic number 36 and atomic mass 83.798. It is colorless and odorless noble gas with applications in photography and lighting. Unfortunately the high cost of obtaining krypton from the air has limited its practical use.
