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.

Yes, the answer is A

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
