	xenon — FactMonster.com
		Xenon is used in certain photographic flash lamps, in high-intensity arc lamps for motion picture projection, and in high-pressure arc lamps to produce ultraviolet light.
		A mixture of stable and unstable isotopes of xenon is produced in nuclear reactors during neutron fission of uranium; one of these, xenon-135, is a very good neutron absorber and must be removed since it poisons the reaction.
		Xenon was discovered spectroscopically in 1898 by William Ramsay and M. Travers, who obtained it by fractional distillation of an impure sample of krypton.

		Xenon - Xe - Compressed gas purity, properties and packaging - Xenon is used as a light source in special applications and an important application is as a fill for thyratron and half-wave rectifier tubes.
		Xenon occurs in slight traces in gases within the Earth and is present to an extent of about 0.0000086 percent, or about one part in 10,000,000, by volume of dry air.
		Natural xenon is a mixture of nine stable isotopes in the following percentages; xenon-124 (0.096); xenon-126 (0.090); xenon-128 (1.92); xenon-129 (26.44); xenon-130 (4.08); xenon-131 (21.18); xenon-132 (26.89); xenon-134 (10.44); and xenon-136 (8.87).

	PlanetPapers - Why Xeon Doesn't React
		Xenon was long considered incapable of chemical reaction, but in 1962 Neil Bartlett, a Canadian chemist, reported synthesis of xenon hexafluoroplatinate, XePtF6, a true compound.
		Now, xenon's reported compounds are sodium perxenate, xenon deutetrate, xenon hydrate, difluoride, tetrafluride and hexafluoride.
		Xenon as well as the other noble gasses require an incredible amount of pressure for them to react, which makes them very inert since such a large amount of pressure does not occur naturally.

		Xenon hexafluoroplatinate is the description of the product from the first chemical reaction for a noble gas.
		The title compound is ionic, consisting of an octahedral anionic fluoride complex of platinum and various xenon cations.
		It has been proposed that the platinum fluoride structure forms a negatively charged polymeric network with xenon or xenon fluoride cations held in its meshes.

	Neil Bartlett Summary
		After devising special techniques to study the solid, Bartlett and D. Lohmann determined that it was a actually a salt, dioxygenyl hexafluoroplatinate, and the first compound to contain both positively and negatively charged ions.
		While he is best known for his work with noble gases, Bartlett's other research includes preparing new synthetic metals from graphite or graphite-like boron nitride; synthesizing salts containing perfluoroaromatic cations; preparing new binary fluorides, and discovering, with B. Zemva and his co-workers, a new method of synthesizing thermodynamically unstable high oxidation state fluorides.
		This contradicted all ideas chemists had of the nature of valency, as it was assumed that xenon, like all noble gases, was totally inert to chemical combination.
