I Bonding between two atoms lowers the potential energy of the two atoms

1. Bond strength correlates to how much potential energy of the atoms is lowered from bonding.

II There are different types of bonding that occurs among molecules:

1. ionic bonding (metal − nonmetal)
2. covalent bonding (nonmetal − nonmetal)
3. metallic bonding (metal – metal)
