| 1 | There is a Coulombic force of attraction. | |
| 2 | The attractive energy is just the potential energy, Coulombic potential. | |
| 3 | This is coulombs per charge and this is coulombs per mole. | |
| 4 | It bears a negative charge and the value of minus 1.6 times 10 to the 19 coulombs. | |
| 5 | Coulomb, in France, found the same law for electric charges. |
