| combustion | a chemical change in which oxygen reacts with another substance, often producing energy in the form of heat and light |
| oxidation | complete or partial loss of electrons or gain of oxygen |
| oxidizing agent | a substance that accepts electrons in a redox reaction |
| corrosion | oxidation of metals to metallic ions by oxygen and water in the environment |
| zinc | a metal that loses electrons easily |
| gold | a metal that resists corrosion |
| reducing agent | a substance that releases electrons in a redox reaction |
| spectator ions | ions that are present but do not participate in or change during the reaction |
| oxidation half-reaction | Fe^2+ -> Fe^3+ + e- |
| half-reaction method | balancing a redox equation by first balancing the oxidation and reduction half-reactions |
| oxidation-number change method | balancing a redox equation by comparing the increase and decrease in oxidation numbers |
| half reaction | equation showing either the reduction or the oxidation of a species in an oxidation-reduction |
| oxidation-reduction reaction | a reaction that involves the transfer of electrons between reactants during a chemical change |
| oxidizing agent | the substance in a redox reaction that accepts electrons |
| reduction | a process that involves a complete or partial gain of electrons or the loss of oxygen; it results in a decrease in the oxidation number of an atom |
| oxidation number | a positive or negative number assigned to a combined atom according to a set of arbitrary rules |
| oxidation | a process that involves complete or partial loss of electrons or a gain of oxygen; it results in an increase in the oxidation number of an atom |
| redox reaction | another name for an oxidation-reduction reaction |
