Xenon Compounds
Xenon (stranger in Greek) was discovered by Ramsay & Travers in 1898.  For many years it had been assumed that xenon and other noble gases were inert but in 1962 Neil Bartlett at the University of British Columbia treated xenon gas with PtF6 and prepared the first noble gas compound consisting of platinum, fluorine and xenon. More than 80 xenon compounds have been made with xenon chemically bonded to fluorine and oxygen.
