But since its un-named does that mean that they havent proven it to be an actaul element?

Turns out that Uuo Ununoctiom doesn't exist as they retracted it: http://enews.lbl.gov/Science-Articles/Archive/118-retraction.html

I also just found this website, dont know how useful it is but it gives information on all the elements:http://www.webelements.com/webelements/elements/text/periodic-table/key.html
