NEET Chemistry Orbitals MCQ Question

Type: MCQ-fact-Medium-Class 11

What is the reason for the extra stability of completely filled and half-filled subshells?

A

Symmetrical distribution of electrons

B

Higher energy levels of the orbitals

C

Increased number of orbitals

D

Lower nuclear charge attraction

Correct Answer

Option A

Detailed Explanation

The extra stability associated with completely filled and half-filled subshells arises from their symmetrical distribution of electrons, which leads to greater stability due to reduced electron-electron repulsion and increased attraction to the nucleus.
