Charge of noble gas ions~

under normal circumstances, noble gases are unreactive.

however, heavy noble gases like xenon has been observed to form compounds under some conditions.

xenon hexafluoroplatinate(VI), Xe(+) [PtF6](-) was synthesized, with xenon cation apparently possessing charge of 1+ ; the nature of the xenon cation is still unknown due to some other physical properties, however.

though noble gases seldom form ions, various covalent compounds have been synthesized with different stability, for krypton Kr, xenon Xe and radon Rn. a compound of argon Ar was reported to be synthesized.

take Xe as example: the oxidation number of Xe in its compounds could be +2, +4, +6 and +8.

Noble gases have a neutral charge (zero), so they usually don't bond naturally.
