129Xe Information
Xenon is a colourless, odourless gas belonging to group 18 on the periodic table (the noble gases). Xenon has 40 isotopes. There are 9 natural isotopes, 7 of which are stable. 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.
Xenon is used for filling flash lamps and other powerful lamps. Electrical excitation of xenon produces a burst of brilliant white light. Also it is used in bubble chambers and modern nuclear power reactors.
