Sounds like an error, surely hydrogen is not a noble gas.
Does anybody have any information about why it is called the "s" block? I believe it is something to do with a german name, but I am not certain. —Preceding unsigned comment added by Viola16 (talk • contribs) 20:50, 29 May 2010 (UTC)
I saw that quite a few "Citation needed"s were attached to basic statements that are a definite given. Example : They are extremely valuable as reducing agents to extract titanium, zirconium, thorium and tantalum from their ores, and have other uses as reducing agents in organic chemistry.[citation needed]
I'm sorry, what?
Why do we need a citation for things so obvious!? With your permission - may we please remove these tags? Neeya The Great (talk) 15:25, 4 November 2011 (UTC)
