Electronic configurations of four elements A, B, C and D are given below

Options

A. `1s^(2), 2s^(2), 2p^(6)`
B. `1s^(2), 2s^(2), 2p^(4)`
C. `1s^(2), 2s^(2), 2p^(6), 3s^(1)`
D. `1s^(2), 2s^(2), 2p^(5)`

Explanation

`np^(5)` and `ns^(1)` elements possess a large tendency to accept the electron than fully and half-filled elements
