These elements have noble gas structures (???)
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)
- "S" is short for "sharp". It's a bit of old terminology from spectroscopy, and the names are descriptive of the spectral lines observed. Lanthanum-138 (talk) 11:00, 16 March 2011 (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.
I'm sorry, what?
