Since it is a 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.
