Xenon (ZEN-on or ZEE-non)is a noble gas. Since it is an almost completely unreactive, it is often used in industrial processes as a coolant. However, in 1962, Xenon was shown to react with Fluorine, to produce Xenon Hexafluoride. Due to the masses of the heavier noble gases, it fulfills the prediction that heavier noble gases should be able to react.
