Q. Study the orbital diagrams of two atoms 'X' and 'Y'. Which subshell will be more stable and why?
NTA Abhyas
NTA Abhyas 2020
Structure of Atom
A
X, exchange energy is maximum, so is stability
63%
B
Y, exchange energy is maximum, so is stability
5%
C
X, exchange energy is minimum, so stability is maximum
15%
D
Y, exchange energy is minimum, so stability is maximum
17%
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.
