Answer 2

Not B and not D for sure.

Answer 3

The answer is C - It will give up its valence electron to the other atom.

For example, one valence electron sodium, Na, combines with seven valence electron Chlorine, Cl.

Both atoms want to have a complete 8 valence electron outer shell. Sodium wants to lose its one valence electron and chlorine wants to gain one. So the sodium gives up its electron to the chlorine to form sodium chloride, an ionic salt.
