Problem

What is the best explanation for the fact that the ionization energy of boron is lower than that of beryllium?

1. the quantum mechanical stability of the filled s subshell of beryllium

2. the increased repulsion experienced by the electrons in beryllium

3. boron has a larger effective nuclear charge than beryllium.

4. the radius of boron is smaller than that of beryllium making it easy to remove an electron
