| do alkali metals take part in electrochemical cells without metals? | no, they are spectator ions |
| what is an electrolyte | electrically conducting solution containing ions |
| what does movement of ions in the electrolyte do? | complete the circuit |
| How can a simple cell be made? | placing two metals in an electrolyte |
| how do electrons and ions move in a simple cell? | electrons move through voltmeter from metal higher up in electrochemical series to metal lower Ions move in the electrolyte to balance up this movement of charge |
| how can electricity be produced in a half cell? | connecting two different metals in solutions of their metal ions |
| describe the movement of electrons in a half cell/external circuit | electrons flow in the external circuit from the metal higher in the electrochemical series to the one lower |
| what kind of voltage do two metals far apart in the electrochemical series produce? | a high voltage in an electrochemical cell |
| do alkali metals take part in electrochemical cells without metals? | no, they are spectator ions |
