Question

Group 15 elements have more electron gain enthalpy than group 16 -elements. The correct reason for this is (A) Half -filled stability of gp. 15 elements (B) Poor shielding in gp. 15 elements (C) Poor shielding in gp. 16 elements (D) Half -filled stability of gp. 16 elements

Tardigrade Admin · Accepted Answer

The atoms having half-filled and fully filled orbitals are comparatively more stable, hence more energy is required to remove the electron from such atoms. Therefore group 15 have more I.E. than gp. 16 elements.

Q. Group $15$ elements have more electron gain enthalpy than group $16$ -elements. The correct reason for this is

Half -filled stability of gp. 15 elements

Poor shielding in gp. 15 elements

Poor shielding in gp. 16 elements

Half -filled stability of gp. 16 elements

The atoms having half-filled and fully filled orbitals are comparatively more stable, hence more energy is required to remove the electron from such atoms. Therefore group $15$ have more I.E. than gp. $16$ elements.
