Electronic configurations of few elements are given below, Mark the incorrect match.

Options

A. `1s^(2)2s^(2)2p^(5)` -Most electronegative element
B. `1s^(2)2s^(2)2p^(3)`-An element belonging to `3^(rd)` period and `5^(th)` group
C. `1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(8)4s^(2)`-A d-block element
D. `1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)`-An element from `18^(th)` group

Answer

B

Explanation

Since n=2 it belongs to `2^(nd)` period.
