When are atoms reactive? An atom is reactive if its outer ring is incomplete. In general, an atom is reactive if it has less than 8 electrons in its outer ring.

Why do nonmetal atoms make covalent bonds? They bond to have a complete outer ring of electrons. They bond to become like the noble gasses.

What happens to the number of electrons surrounding an atom after it bonds with another atom? The ring becomes complete.
