Oxidation is the loss of electrons by a reactant. Reduction is the gain of electrons by a reactant LEO the lion goes GER! LEO: Losing Electrons during Oxidation GER: Gaining Electrons during Reduction Redox Reactions Redox Reactions In a balanced redox reaction, the total number of electrons lost by one substance is the same as the total number of electrons gained by the other. Oxidizing agent ? the substance that accepts the electrons. Reducing agent ? the substance that gives up the electrons.
