How does the formation of a covalent bond lower the potential energy of the two atoms in the bond? Hints How does the formation of a covalent bond lower the potential energy of the two atoms in the bond?

A)Forming a covalent bond transfers an electron from a metal to a nonmetal, which creates a favorable interaction between the resulting ions.

B)The lowest potential energy occurs when the two nuclei are an optimum distance apart from one another so that they don't repel each other.

C)The potential energy is lower when the valence electrons lie in between the positively charged nuclei than when they are close to only one nucleus.

D)Forming a covalent bond releases electrons from the atoms, which lowers the potential energy of the atoms.
