Which one of the following is the weakest kind of the bonding in solids?

Show answer and solution

Answer: (c)

Ionic, covalent and metallic bonds have binding energies of a few eV per atom.
Van der Waals forces come from weak induced dipole attractions, about 0.01–0.1 eV, much weaker.
So the answer is (c) van der Waals.
