Metals normally lose electrons to non-metals, which accept those electrons. Therefore, metals are said to be electron donors while non-metals are electron acceptors. In this case, metals can be termed as reducing agents, because they donate electrons which, when accepted by non-metals, tend to lower their oxidation numbers.
