$(A)\,S_{\left( g \right)}^ - \,\, \to \,\,S_{\left( g \right)}^{2 - }\,$
$(B)\,Na_{\left( g \right)}^ + \, + \,Cl_{\left( g \right)}^ - \,\, \to \,\,NaCl\,(s)$
$(C)\,{N_{\left( g \right)}}\, \to \,\,N_{\left( g \right)}^ - $
$(D)\,Al_{\left( g \right)}^{2 + }\, \to \,\,Al_{\left( g \right)}^{3 + }$
$b.$ $Na _{( g )}^{+}+ Cl _{( g )}^{-} \rightarrow NaCl _{( s )}$ Lattice energy (exothermic)
$c.$ $\quad N _{( g )} \rightarrow N _{( g )}^{-}$ (Half filled p-subshell)
$d.$ $Al _{\text {(g) }}^{2+} \rightarrow Al ^{3+}_{( g )}$ (endothermic as ionization is endothermic)
