Chemical Bonding - Practice Questions Multiple Choice Identify the choice that best completes the statement or answers the question. The valence electrons are the electrons that participate in chemical bonding. Metal + nonmetal = ionic bond. The fact that the second and third bonds (π bonds) are weaker than the first (σ bond) needs to be emphasized. The amount of energy needed to separate a gaseous ion pair is its bond energy. There are three general types of chemical bonds: ionic, covalent, and metallic.
