xenon

Chemistry

A colourless odourless gas belonging to group 18 of the periodic table (see noble gases); a.n. 54; r.a.m. 131.30; d. 5.887 g dm⁻³; m.p. –111.9°C; b.p. –107.1°C. It is present in the atmosphere (0.00087%) from which it is extracted by distillation of liquid air. There are nine natural isotopes with mass numbers 124, 126, 128–132, 134, and 136. Seven radioactive isotopes are also known. The element is used in fluorescent lamps and bubble chambers. Liquid xenon in a supercritical state at high temperatures is used as a solvent for infrared spectroscopy and for chemical reactions. The compound Xe⁺PtF₆⁻ was the first noble-gas compound to be synthesized. Several other compounds of xenon are known, including XeF₂, XeF₄, XeSiF₆, XeO₂F₂, and XeO₃. Recently, compounds have been isolated that contain xenon–carbon bonds, such as [C₆H₅Xe][B(C₆H₅)₃F] (pentafluorophenylxenon fluoroborate), which is stable under normal conditions. The element was discovered in 1898 by Sir William Ramsay and Morris Travers.
