Q. A sudden large jump between the values of second and third ionisation energies of an element would be associated with the electronic configuration
A) $1s^{2},\ 2s^{2},\ 2p^{6},\ 3s^{2}$
B) $1s^{2},\ 2s^{2},\ 2p^{6},\ 3s^{1}$
C) $1s^{2},\ 2s^{2},\ 2p^{6},\ 3s^{2},\ 3p^{1}$
D) $1s^{2},\ 2s^{2},\ 2p^{6},\ 3s^{2},\ 3p^{2}$
Explanation
(a)
$1s^{2},2s^{2}p^{6},\ 3s^{2} -$ In III transition $e^{-}$ is to be removed from stable configuration
