Yes, I know it's a stable element (from the column of the stable gases. Yeah, I remember something from high school
But now that I saw Malone's question and your answer, I became curious about that. Why you choose Xenon? I mean, why another element would not be useful? (not another stable gas). Isn't there any other that could be used??
And why not any other stable gas (Helium, for example. Neon maybe) ? Probably Xenon is not the cheaper thing you can buy at Joe's shop.
