Question

If an atom has 1 to 3 valence electrons, what will it do?

Answer 1

Answer:

$\boxed{\text{donate electrons}}$

Explanation:

An atom with one to three valence electrons would have to gain seven to five valence electrons, respectively to get a stable octet.

It is easier for it to donate electrons and expose the stable octet of electrons in the shell below..

(A) is wrong. You can't move electrons to a lower shell, because it's already full.

(B) is wrong. The atom will donate electrons.

(C) is wrong. Moving electrons to a higher shell will make the atom more unstable.
