Which of the following electronic configuration corresponds to an inert gas?

Options

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

Answer

B

Explanation

`1s^(2) 2s^(2) 2p^(6)` is the electronic configuration of Neon `(""_(10)Ne)` (Inert gas).
