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.
Answer
X, exchange energy is maximum, so is stability.
Explanation
Solution
: 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.
