... Since electrons have a negative charge, and atom with a negative oxidation number will gain electrons. That means an atom with a positive oxidation number will lose electrons. Nonmetals and polyatomic ions almost always gain electrons - have negative oxidation numbers. Metals almost always lose elec ...
