The direct reaction of xenon with fluorine leads to a series of compounds with oxidation numbers $+2,+4$ and $+6$ . XeF $4$ reacts violently with water to give $\mathrm{XeO}_3$. The compounds of xenon exhibit rich stereochemistry and their geometries can be deduced considering the total number of electron pairs in the valence shell.
