Total number of enthalpy(s) (out of given eight) of $\mathrm{A}\left(\mathrm{g}\right)$ which is/are not associated with conversion of ${\mathrm{A}}_{\left(\mathrm{g}\right)}^{-}\to {\mathrm{A}}_{\left(\mathrm{g}\right)}^{+4}$ :

${\mathrm{IE}}_1, {\mathrm{IE}}_2, {\mathrm{IE}}_3, {\mathrm{IE}}_4, {\mathrm{IE}}_5, {\mathrm{IE}}_6, {\mathrm{EGE}}_1, {\mathrm{EGE}}_2$

($\mathrm{IE}=$ ionization energy, $\mathrm{EGE}=$ electron gain enthalpy)
