First ionization energies for B = 801 kJ/mol and Al = 578 kJ/mol.
The ionized electron for B comes from the second energy level, which is at a lower energy state than the ionized electron from Al, which comes from the third energy level ∴ it takes more energy to ionize.

For Na, the first ionization energy I1 = 495 kJ/mol and second ionization energy I2 = 4562 kJ/mol
I2 is much larger than I1 because the second ionized electron comes from the core rather than valence shell.

Why Nitrogen is smaller than Be.
N experiences an effective nuclear charge of +5 (Zeff=7-2=5), Be Zeff= +2. The valence e- of N are “feeling” the pull of 5 protons as opposed to 2 e- for Be

The electron affinities for Mg > 0 and Na = -53 kJ/mol.
The added electron to Mg must go into a higher energy state (3p) compared Na (3s) ∴ the loss in energy when an electron approaches a nucleus is offset by the electron's higher energy level.
