comments[edit]

How about listing some of the ways that a helium-containing fullerene differs from a regular one.. I'm tempted to assume its at least a little more dense, and judging from the claimed yields (0.1%)it seems like it would have been possible to make enough to measure this?

Also, if the difference is purely the weight of the compound, is He@C60 as difficult to separate from the rest of the C60 as, say, separation of atomic isotopes from one another? Zaphraud (talk) 08:18, 22 February 2009 (UTC)

XeOxY2[edit]

Let's not use "Y". It implies yttrium, and while that would be interesting, it's misleading notation. Change to "Z", which represents no element? 72.178.12.19 (talk) 02:04, 20 October 2009 (UTC)

Done. WP:BOLD.—Tetracube (talk) 02:44, 20 October 2009 (UTC)
Okay. I've added a note about noble gas cations, which pop up as unverified claims on all the noble gas pages. 72.178.12.19 (talk) 02:59, 23 October 2009 (UTC)
We need some cite to at least verify that there are such claims. DMacks (talk) 03:00, 23 October 2009 (UTC)
Of course there are cations consisting of two noble gas atoms. But I don't know much about them other than that they formally have a three-electron bond with a bond order of 0.5, so I'll leave adding that information to someone with more time and/or inclination. You can find lots of references very easily in google scholar and google books: [1], [2], [3], etc. I'm not sure I would call these "compounds" in the usual sense of the word, but I think they deserve some mention in this article because they illustrate some of the issues with bonding in noble gases. --Itub (talk) 13:50, 23 October 2009 (UTC)
