Chemistry Question on Group 15 Elements
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
C
Poor shielding in gp. 16
D
Half -filled stability of gp. 16 elements
Answer
Half -filled stability of gp. 15 elements
Explanation
Solution
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.
