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

- X, exchange energy is maximum, so is stability.
- Y, exchange energy is maximum, so is stability.
- X, exchange energy is minimum, so stability is maximum.
- Y, exchange energy is minimum, so stability is maximum.
Answer
(B) Y , exchange energy is maximum, so is stability.
