5. chemical bonds are likely to form when
a) an atom’s outer energy level doesn’t have the maximum number of electrons
b) an atom’s outer energy level is filled to capacity
c) an atom’s nucleus has the same number of protons as it does neutrons
d) two atoms have the same number of electrons

B

Explanation:

Chemical bonds are formed to lower potential energy by sharing electrons between atoms. However, a covalent bond is when there is unequal sharing of electrons and a nonpolar covalent bond is when there is equal sharing of electrons.
