Answer:

By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase. Q1. On the basis of periodic trends, determine the element with the higher first ionization energy in each pair (if possible).

The first ionization energy of magnesium is larger than sodium because magnesium has one more proton in its nucleus to hold on to the electrons in the 3s orbital.
