| Cell | Ion Formed | Reasoning |
| Sodium (Na) | Na+ | Sodium readily loses one electron to achieve a stable, filled outer shell configuration. This results in a +1 charge. |
| Aluminium (Al) | Al3+ | Aluminium readily loses three electrons to achieve a stable, filled outer shell configuration. This results in a +3 charge. |
| Sulfur (S) | S2- | Sulfur readily gains two electrons to achieve a stable, filled outer shell configuration. This results in a -2 charge. |
