Q. The electric configuration of element with atomic number 24 is
A) $1s^{2},2s^{2}2p^{6},3s^{2}3p^{6}3d^{4},4s^{2}$
B) $1s^{2},2s^{2}2p^{6},3s^{2}3p^{6}3d^{10}\$
C) $1s^{2},2s^{2}2p^{6},3s^{2}3p^{6}3d^{6}$
D) $1s^{2},2s^{2}2p^{6},3s^{2}3p^{6}3d^{5},4s^{1}$
Explanation
(d)
The electronic configuration of element with atomic number 24 is
$1s^{2},\ 2s^{2},2p^{6},3s^{2},3p^{6},4s^{1},3d^{5}$
($\because$Exactly half-filled orbitals are more stable than nearly half-filled orbitals.)
