Yes, you're correct, but in order to oxidize any noble gas, you need a very strong oxidizing agent. Generally, the noble gases used are krypton and xenon, which are (generally) reacted with fluorine. The smaller noble gases -- helium, neon, and argon -- are very difficult to oxidize, because their electrons are pretty close to the nucleus. The larger krypton and xenon molecules can be oxidized, however, because the electrons are farther from the nucleus, so they aren't attracted nearly as strongly to the nucleus as those of the smaller noble gases.

And yes, if somebody else has the answer to a question posed, they're more than welcome to answer it.
