Which of the electronic configuration is of a noble gas atom in the following ?

Options

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

Answer

C

Explanation

Except helium all the noble gas atoms have stoble octet `(ns^(2),np^(6))` in their outermost shell.
