From the ground state electronic configuration of the elements given below, pick up the one with the highest value of second ionisation energies

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)`

D

`1s^(2), 2s^(2)2p^(5)`

Text Solution

Verified by Experts

The correct Answer is:
B
Electronic configuration of `(b)` corresponds to `Na ( Z = 11)`, so it will have the highest `IE_(2)` among the given configuration. Because the 2nd `e^(-)` has to be removed from the full - filled stable `2p^(6)` configuration.
