Question

Elaborate on the differences between metals and noble gases.

A) Noble gases have a full shell of valence electrons while metals have only a few valence electrons.
B) Valence electrons are different - metals have a full shell while noble gases have less than half a shell.
C) Metals have a nearly full shell of valence electrons while noble gases have a half shell of valence electrons.
D) All electrons are different - noble gases have a full shells while noble gases have greater than half shells.

Answer 1

The answer is A.
Nobel gases have full shell of valence electrons, that is why they tend to not enter any chemical reactions because they are satisfied while metals have very few electrons in the valence shell, so they are active in any chemical reaction.

Hope this helps.

Answer 2

Yes, the answer is A
