Chemically, perxenates are used as an oxidizing agent, and xenon is also used in protein crystallography. of xenon compounds have been found and studied. It reacts with water or hydrogen to form xenon. XeF6 is the strongest fluorinating agent of the series. To find the correct oxidation state of Xe in XeF6 (Xenon hexafluoride), and each element in the molecule, we use a few rules and some simple math. The symptoms include fatigue, emotional instability, air hunger, convulsions, and nausea. { XeO }_{ 4 } + { XeF }_{ 6 } → { XeOF }_{ 4 } + { XeO }_{ 3 }{ F }_{ 2 }, { XeO }_{ 4 } + 2{ XeF }_{ 6 } → 2{ XeOF }_{ 4 } + { XeO }_{ 2 }{ F }_{ 4 }. { XeF }_{ 6 } + 3{ H }_{ 2 }{ O } → { XeO }_{ 3 } + 6HF, 6{ XeF }_{ 4 } + 12{ H }_{ 2 }{ O } → 2{ XeO }_{ 3 } + 4{ Xe } + 3{ O }_{ 2 } + 24HF.
