#### Solution

The electron volt is the amount of energy given to an electron in order to move it through the electric potential difference of one volt.

1 eV = 1.6 × 10^{–19} J

The numerical value of ionisation energy in eV is equal to the ionisation potential in volts. The equality does not hold if these quantities are measured in some other units.
