In
1898, krypton was discovered by Sir William Ramsay and his student, Morris W.
Travers of Great Britain.
Krypton was obtained from residue that was left after liquid air had nearly boiled away water, oxygen, nitrogen, helium, and argon from the sample of air.
Solid krypton is a white crystalline substance with a face-centered structure which is common to all the "rare gases."
It is characterized by its brillant green and orange spectral lines.
Krypton belongs to group 8, titled noble gases, on the periodic table.
Krypton has an atomic number of 36.
The symbol for krypton is Kr.
Naturally occuring Krypton contains six stable isotopes. Seventeen other unstable isotopes are now recognized.
Under normal conditions, krypton is colourless, odourless, and is a fairly expensive gas.
Krypton's electron configuration is [Ar] 3d10, 4s2, 4p6.
Krypton is used with argon as a low-pressure filling gas for flourescent lights. It is also used in some photographic flash lamps for high speed photography and UV-laser spectral line used for international measurement of the metre.
Krypton is a Latin term that means "hidden."
