Xenon Information

Colourless, odourless gas belonging to group 18 on the periodic table (the noble gases.) Nine natural isotopes and seven radioactive isotopes are known. Xenon was part of the first noble-gas compound synthesized. Several others involving Xenon have been found since then. Xenon was discovered by Ramsey and Travers in 1898.

Used for filling flash lamps and other powerful lamps. Electrical excitation of xenon produces a burst of brilliant whtie light. Also used in bubble chambers and modern nuclear power reactors.
