Covelant bonds form when 2 atoms do not have full outer shells.
Both of the 2 atoms then join together and share their electrons in order to gain stability have have a full outer shell
<span>Na (sodium) is highly electropositive. Its has 1 electron in its outermost orbit which is transferred to an electronegative atom to form an ionic bond.
It only needs to get rid of one valence electron to take part in a reaction. That's how it's highly reactive.</span>
A: Atoms and molecules is the correct answer.
