Which of the following is not correct statement for periodic classification of elements?

Options

A. `[Ne]3s^(2)3p^(1)`
B. `[Ne]3s^(2)3p^(3)`
C. `[Ne]3s^(2)3p^(2)`
D. `[Ne]3d^(10)4s^(2)4p^(3)`

Answer

B

Explanation

`[Ne] 3s^(2)3p^(3)`
From left to right in a period, the first ionisation potential increases. Down the group, ionisation potential decreases. In option (c), half-filled stable configuration is also present.
