Post-Transition Metals Elements that lie between transition metals and metalloids on the periodic table; soft, poor mechanical strength, lower melting point than transition metals; chemically classified by covalent bonding patterns, amphoterism, and anionic species formation. Rusting can be prevented by keeping oxygen and water away, and by sacrificial protection. Indium is used in electronics including flat panel displays and touch screens. They are harder and less reactive than the alkaline earth metals. However, the outermost s electrons are always the first to be removed in the process of forming transition metal cations.
