A sudden large jump between the values of second and third ionisation energies of an element would be associated with the electronic configuration

Options

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

Answer

B

Explanation

It is evident that release of 2 electron from the isolated gaseous element shown in option (b) would give rise to highly stable cor eof Ne. Hence, massive energy is required to remove the `3^(rd)` electron.
