The table below provides information about three crystalline ionic compounds containing ions that are isoelectronic with \(\text{Ne}\).

Compound	Cation	Anion
\(\text{NaF}\)	\(\text{Na}^+\)	\(\text{F}^-\)
\(\text{MgO}\)	\(\text{Mg}^{2+}\)	\(\text{O}^{2-}\)
\(\text{AlN}\)	\(\text{Al}^{3+}\)	\(\text{N}^{3-}\)

Which of the following correctly ranks the compounds in order of decreasing melting point, and provides the best justification?
