This element is used in lamps that produce short, intense flashes of light like stroboscopes and high-speed photography. The existence of its 129 isotope in many meteorites suggest that it is a product of the decay of iodine-129. Another isotope of this element, with atomic mass 135, is produced by uranium fission, while its most common isotope has an atomic mass of 132. In 1962, Neil Bartlett formed a red, crystalline solid out of this element's hexafluoroplatinate, and other compounds this elements form include one with Cs2F8 and a series of fluorides, of which the easiest to prepare is (*) tetrafluoride. These compounds all go against the conventional wisdom that

These compounds all go against the conventional wisdom that compounds can not be made from noble gases. First isolated by Sir William Ramsay and Morris Travers in 1898 by fractional distillation of krypton, FTP, name this noble gas with atomic number 54 and chemical symbol Xe.
