Answer:

Here electronic configuration is a dominant character.

Explanation:

Both elements belong to second period of periodic table.

Be has fully filled s orbital whereas B has one valence electron in p subshell. Since half filled or fully filled orbitals are more stable, so its tough to remove electron from Be than B and has high ionization energy.
