Talk:Nonmetal
|
Are the noble gases classified with the nonmetals? Periodic table/Metals and Non Metals says yes, but I don't really see why. They break the periodicity pattern of increasing electronegativity; they might as well be placed to the left of the alkali metals as to the right of the halogens. -Smack 20:46 20 Jun 2003 (UTC)
Metallicity of carbon
Why is carbon a non-metal if it has metallic allotropes?
