- ✓$[Ne]3{s^2}3{p^6}3{d^5},4{s^1}$
- C$[Ne]3{s^2}3{p^6},4{s^2}4{p^4}$
- D$[Ne]3{s^2}3{p^6}3{d^1},4{s^2}4{p^3}$
✓
Answer
Correct option: B.
$[Ne]3{s^2}3{p^6}3{d^5},4{s^1}$
b
(b) $3d$ subshell filled with $5 $ electrons (half-filled) is more stable than that filled with $4$ electrons. $1,\,4s$ electrons jumps into $3d$ subshell for more sability.
