प्रश्न
Which of the following options does not represent ground state electronic configuration of an atom?
पर्याय
1s2 2s2 2p6 3s2 3p6 3d8 4s2
1s2 2s2 2p6 3s2 3p6 3d9 4s2
1s2 2s2 2p6 3s2 3p6 3d10 4s1
1s2 2s2 2p6 3s2 3p6 3d5 4s1
उत्तर
1s2 2s2 2p6 3s2 3p6 3d9 4s2
Explanation:
As per Hund’s rule the half-filled and fully filled orbital leads to extra stability due to the symmetry thus fully filled 3d and half-filled 4s is preferred.
