History edit

In 1933, Linus Pauling predicted that the heavier noble gases would be able to form compounds with fluorine and oxygen. He also predicted the existence of krypton hexafluoride.[2][verification needed][3] Calculations suggest it would have octahedral molecular geometry.[1]

So far, out of all possible krypton fluorides, only krypton difluoride (KrF2) has actually been synthesized.[citation needed]
