I removed a reference to "Smith, 1984," because I could not identify the source. --James S. 07:25, 17 March 2006 (UTC)


Just like iron(III) chloride used to be called "ferric" and iron(II) chloride used to be called "ferrous", uranium(VI) fluoride is "uranic" and uranium(IV) fluoride is uranous. Note that the "ic-ous" nomenclature is outmoded. 08:32, 29 March 2006 (UTC)

This statement supports none of your edits here. --James S. 08:46, 29 March 2006 (UTC)
Huh. And "uranyl" refers to UO22+. Please please please consult a chemistry textbook. 09:24, 29 March 2006 (UTC)

"Ionic states" found in nature[edit]

In nature, one would expect to find uranium in oxidation state +6, the uranyl ion is a thermodynamic sink. Uranium(IV) is common, but only so in the laboratory, when oxygen is excluded. Besides, it's "oxidation state", not "ionic state". 12:09, 29 March 2006 (UTC)

Actually, it is U(IV) that is the thermodynamic minimum. There's a fair bit of oxygen and acid around on the surface of the earth to oxidize the uranium(IV) that is the principle component of uranium-bearing minerals.

What the heck is up with the statement about uranyl once having been thought of as an element? That needs a citation real bad. —Preceding unsigned comment added by (talk) 21:49, 11 January 2010 (UTC)

Major revision[edit]

The article has been extensively revised and extended. I have removed two sections which were unreferenced and mostly irrelevant. Petergans (talk) 20:21, 27 January 2011 (UTC)

Oh jeesh, a problem[edit]

I have been looking for articles that convey really weird information to readers seeking basic info, and this article is another ringer. Maybe some pointy headed academic (me and my friends) see uranyl as a triatomic, but jesus, we dont want regular readers seeing that perspective in the lead-off! We want the real thing, the stuff in solution, with ligands. --Smokefoot (talk) 01:02, 11 April 2011 (UTC)
