There are three main types of chemical bonding: • Ionic bonding. This occurs when a metal bonds with a non-metal (see p. 32). • Covalent bonding. This occurs when two or more non-metals bond (see p. 36). • Metallic bonding. This occurs within metals (see p. 39). Chemical compounds are formed when elements bond by ionic or covalent bonding.
