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)


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? (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. (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)

a few more xenon halides[edit]

XeCl2, XeCl4, XeBr2 are known from the beta decay of 129

Is this a history article or a science article?[edit]

This article needs restructuring to better separate the history from the science. The History and background section does not include the most important events in the history of Noble gas compounds, which were the 1962 discoveries of XePtF6 by Bartlett and of XeF4 by the Argonne group. Instead these are presented in the section Xenon compounds whose first half reads like another history section. But first there is a mysterious section called True noble gas compounds, which raises the question of what are the False noble gas compounds? Presumably these are the Reports prior to xenon hexafluoroplatinate and xenon tetrafluoride - perhaps this section should be called Loosely bound complexes of noble gases or Complexes of noble gas bound by intermolecular forces., with a sentence to say that these were the only compounds known prior to 1962, but not in the title.

The article gives the impression of a breathless review written about 1965 to describe the sensational new xenon compounds. Guys, it's 2015 now, so let's just put the history in one section and write the rest of the article in normal descriptive style.Dirac66 (talk) 18:58, 29 March 2015 (UTC)
