Q. A Mo atom in its ground state has a $4d^{5},5s^{1}$ configuration and a Ag atom $4d^{10},5s^{1}$ configuration. This is because a shell which is half-filled or completely filled is particularly
A) Strongly exchange destabilized
B) Weakly exchange stabilized
C) Weakly exchange destabilized
D) Strongly exchange destabilized
Explanation
(d)
A subshell having nearly half-filled or nearly completely filled configurations tends to acquire exactly half-filled or exactly completely filled nature to have lower energy level in order to attain extra stability
