The electronic configuration of the atom having maximum difference in first and second ionzation enthalpies is

Options

A. `1s^(2)2s^(2)2p^(6)3s^(1)`
B. `1s^(2)2s^(2)3s^(2)`
C. `1s^(2)2s^(2)2p^(1)`
D. `1s^(2)2s^(2)2p^(6)3s^(2) 3s^(3)`

Answer

C

Explanation

The atom should have one electron more than the nogle gas configuration i.e., option (A) is correct.
