# What is the difference between "ionization energy", and "ionization potential"?

$M \left(g\right) \rightarrow {M}^{+} \left(g\right) + {e}^{-}$ $\Delta H$ $=$ $\text{Ionization energy}$
The ionization potential is this energy measured in electron volts. $1$ $e V$ $=$ $96.485$ $k J \cdot m o {l}^{-} 1$.
