| 9678332457 | Reduction | The gain of electrons |  | 0 |
| 9678332458 | Oxidation | The loss of electrons |  | 1 |
| 9678332459 | Oxidation Numbers | Indicates the number of electrons lost, gained, or shared as a result of chemical bonding. Higher: Less electrons/less negative Lower: More electrons/more negative |  | 2 |
| 9678332460 | Electrochemical Cell | Any device that converts chemical energy into electrical energy or electrical energy into chemical energy |  | 3 |
| 9678332461 | Voltaic Cell | in which a spontaneous chemical reaction produces a flow of electrons( +G) |  | 4 |
| 9678332462 | Electrolytic Cell | cell that requires an electric current to force a chemical reaction to occur (-G) |  | 5 |
