# How do endothermic processes affect forming a cation from an atom in the gas phase?

May 30, 2018

Is this not inherently an endothermic process?

#### Explanation:

$M \left(g\right) + \Delta \rightarrow {M}^{+} \left(g\right) + {e}^{-}$

It is reasonable that such a process an endothermic given that we have to separate charge.

And for the elements there data are listed in the tables of ionization enthalpies....
