Xenon is a rare, colorless, odorless, tasteless, chemically unreactive gas. It is one of the inert gas elements found in group 0 of the periodic table. 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. Before 1962, people thought that xenon and other noble gases were unable to form compounds. Now, xenon"s reported compounds are sodium perxenate, xenon deutetrate, xenon hydrate, difluoride, tetrafluride and hexafluoride. Xenon is present in the atmosphere in extremely low concentration about one part in 20 million. It is obtained...
of an impure sample of krypton. 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.
