WebDec 5, 2024 · Lets start by looking at a very simple reaction, that of iron and oxygen to form Iron (III) oxide. 2Fe (s) + 3O 2 (g) --> 2Fe +3 + 3O -2 = Fe 2 O 3 (s) In this reaction the iron is getting oxidized because each iron atom loses three electrons and the oxygen is getting reduced because each oxygen gains two electrons.
