A student compares the first ionization energies and valence-electron configurations of two pairs of Period 3 elements.

Element	Valence-electron configuration	First ionization energy \(\text{(kJ/mol)}\)
\(\text{Mg}\)	\([\text{Ne}]3s^2\)	\(738\)
\(\text{Al}\)	\([\text{Ne}]3s^2 3p^1\)	\(578\)
\(\text{P}\)	\([\text{Ne}]3s^2 3p^3\)	\(1{,}012\)
\(\text{S}\)	\([\text{Ne}]3s^2 3p^4\)	\(1{,}000\)

The student observes that the first ionization energy decreases from \(\text{Mg}\) to \(\text{Al}\) and from \(\text{P}\) to \(\text{S}\). Which row correctly predicts the electronegativity comparison for each pair?
