Please fix these typos:

Is there any reason why there is Ununennium? An undiscovered element? If the reason is "for when it gets discovered", then at least three should be added. Uue, Ubn, Ubu. 210.4.230.182 (talk) 14:56, 11 September 2010 (UTC)

Shouldn't Copernicium be in red, not purple? I think it's stable enough to be considered that--even it's non-metastable state (8.9 minutes) has a half life of nearly 5 minutes. Dayshade (talk) 21:15, 20 October 2011 (UTC)

Actually, I seem to have misread about the 5 minutes one, but there is still that metastable one with 8.9 minutes. However, it's not proven. Dayshade (talk) 21:52, 20 October 2011 (UTC)

There seems to be a bit of inconsistency, actually. After research, I found out that some facts (like the isotopes page and text inside the article) claim 4.2 minutes and others claim 3.9 seconds (like the infobox which has a reference) for Copernicium-283.
