The extra stability of half-filled and completely-filled subshell is due to

A

relatively small shielding

B

smaller coulombic repulsion enegry

C

larger exchange enegry

D

all of these

Text Solution

Verified by Experts

The correct Answer is:
D
Electrons in the same subshell have equal enegry but different spatial distribution. Consequently, their shielding of one another is relative small.
