Question:
Group 15 elements have more electron gain enthalpy than group 16-elements. The correct reason for this is
Group 15 elements have more electron gain enthalpy than group 16-elements. The correct reason for this is
Updated On: Mar 30, 2024
- Half -filled stability of gp. 15 elements
- Poor shielding in gp. 15
- Poor shielding in gp. 16
- Half -filled stability of gp. 16 elements
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
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.

Concepts Used:
Group 15 Elements
Group 15 elements are also known as nitrogen group elements or nitrogen family.
It consists of:
- Nitrogen (N)
- Phosphorus (P)
- Arsenic (As)
- Antimony (Sb)
- Bismuth (Bi)
- Moscovium (Mc)
They are present on the right side of the periodic table. All the elements are arranged based on their atomic weight. The elements with similar properties reside in a column called the group.
All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is the principal quantum number.
