HKrCCH sounds like a Klingon swear word. ;-)
Noble gas chemistry maybe shouldn't be termed chemistry - because the compounds produced are very unstable and often only last for short timeframes, even at a few Kelvin from absolute zero. Its main aim is to expand our understanding of how the physics behind chemistry works. Then we can build new theories. Because, to be honest, many fundamental chemistry theories are a "bit dodgy".
Covalent theory is the one I was brought up with, and describes how atoms combine into molecules. However, chemists quickly found that it doesn't account for many things, one being the chemistry of boron, another being the fact that noble gases can actually form compounds with that stable electron configuration.
So research into noble gas chemistry, though seemingly pointless from a practical point of view, stretches the parameters of what we know about quantum physics as it pertains to the atom. And with it we can build new theories.
Now I really want to know two things: whether radon is the last of the noble gases or whether there is another one lurking in the transuranics. Secondly, how Blobrana got a stain on her dress. ;-)
