Caleb Casey · Answer 1

Valence electrons are in the outermost area, have the highest energy, and are all electrons of the atom. This would be A, C and D. B might be a variable, as the Alkali Metals are highly unstable.

Electrons described by E are in Ground State.

Birdy · Answer 2

Answer choice A, B, and C is right about the valence electrons. For answer choice D and E, Would in it be a more of an element kind of choice. whether the element is closer to the left side of the periodic table or not determines the high and low energy.
