That means this atom loses two electrons and this atom gains those same two electrons. So this is our oxidized atom and our reduced atom or our reducing agent and oxidizing agent. So let's go to step one and let's see our two half reactions. So our oxidation half reaction is the following. Our solid iron becomes a positively charged molecule plus two electrons because it releases those two electrons while our cadmium aqueous atom gains those two electrons forming our cadmium solid. So this is our reduction reaction and oxidation reaction.
