Study the orbital diagrams of two atoms 'X and Y'. Which subshell will be more stable and why?

A

X, exchange energy is maximum, so is stability.

B

Y, exchange energy is maximum, so is stability.

C

X, exchange energy is minimum, so stability is maximum.

D

Y, exchange energy is minimum, so stability is maximum.

Text Solution

Verified by Experts

The correct Answer is:
A
In 'X' one electron can exchange energy with 5 orbitals while in 'Y' energy exchange is between 3 orbitals hence half-filled orbitals are more stable.
