#M^(+)(g) + Delta rarr M^(2+)(g) + e^-#

Explanation:

The 2nd ionization energy is the energy associated with the given reaction. This is reasonably an ENDOTHERMIC reaction, even if we were dealing with the 2nd ionization energy of a Group 2 metal.

As with all ionization energies, both product and reactants are specified to be in the gaseous state.
