Oxidation and Reduction Oxidation is the Loss of Electrons E.g., something that is oxidized in the course of a chemical reaction with Oxygen has had electrons stolen by Oxygen Reduction is the Gain of Elections E.g., a gain of electrons results in a decrease (reduction) in electrical charge (since electrons carry a negative charge) Metal ores are “Reduced” to metals (via the addition of electrons)—metals found in ores are in an oxidized form relative to metals found as metals
