| Anode | the electrode in an electrochemical cell where oxidation takes place; the electrode in an electrochemical cell from which metal atoms lose electrons |
| Cathode | the electrode in an electrochemical cell where reduction takes place; the electrode in an electrochemical cell at which metal ions gain electrons |
| Electrode | an electrically conductive surface (usually a metal) that allows electrons to be transferred between reactants in an electrochemical cell |
| Electrochemical Cell | (Galvanic/Voltaic) a device that converts chemical energy into electric current or (Electrolytic) a device that uses electric current from an external source to drive a chemical reaction |
| Electrolytic Cell | an electrochemical call that uses electric current to drive a chemical reaction |
| Galvanic or Voltaic Cell | an electrochemical cell that spontaneously generates electrical energy; an electrochemical cell that converts chemical energy into electric current; a battery |
| Oxidation | the loss of one or more electrons by an atom, molecule, or ion |
| Oxidation Half Reaction | the part of a redox reaction that involves the loss of one or more electrons |
| Oxidation Number | the charge on an atom of an element within a compound |
| Oxidizing Agent | the species that gains one or more electrons in an electrochemical reaction; the species that oxidizes another substance in a redox reaction |
| Redox | an electrochemical reaction; an oxidation-reduction reaction |
| Reducing Agent | the species that loses one or more electrons in an electrochemical reaction; the species that oxidizes another substance in a redox reaction |
| Reduction | the gain of one or more electrons by an atom, molecule, or ion |
| Reduction Half Reaction | the part of redox reaction that involves the gain of one or more electrons |
| Salt bridge | a tube filled with ionic solution or gel that allows ions to flow between two separate half-cells in a voltaic cell, preventing a build-up of charge and allowing the continuous flow of electrons from anode to cathode |
