Question

Berilium has higher IP than boron.Why?

Answer 1

The first ionization of Beryllium is greater than that of Boron because beryllium has a stable complete electronic configuration(1s2 2s2)so it requires more energy to remove the first electron from it......whereas boron has the electronic configuration(1s2 2s2 3s1)which needs lesser energy than that of beryllium to remove the valence electron.

Answer 2

Answer:

       Beryllium has a higher Ionization energy than Boron because of increased stability due to half filled and fully filled orbitals. The electrons in the 2s orbital are already paired and hence it is quite a stable configuration for the beryllium atom .
