Question

Ionization potential of Be and N is higher than its neighbors.​

Answer 1

Answer:

extra stability of half filled orbitals

The electronic configurations of N and O are 1s22s22p3 and 1s22s22p4 respectively. Nitrogen has a stable half-filled 2p orbital. It requires more energy to remove an electron from such stable configuration.

Answer 2

The ionization potential of Be and N is higher than its neighbors due to the higher stability of half-filled and fully filled orbitals.

Explanation:

Ionization potential can be defined as the amount of energy required to remove an electron from an isolated gaseous atom.

• The electronic configuration of Be is 1s² 2s².
• The 2s orbital of Be is fully filled and highly stable. Thus, more amount of energy is required to remove an electron from a fully filled stable orbital.

Similarly,

• The electronic configuration of N is 1s² 2s² 2p³.
• The 3p orbital of N is half-filled which means it has extra stability. Thus, more amount of energy is required to remove an electron from a half-filled stable orbital.

Hence, the ionization potential of Be and N is higher than its neighbors.​
