The second ionization energy of Mg is than its first ionization energy, and is than the second ionization energy of Na.

1. Larger

2. Larger

Explanation:

The second ionization energy of Mg is larger than the first because it always takes more energy to remove an electron from a positively charged ion than from a neutral atom.

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.
