Which of the following noble gases has a full shell(s) of electrons?

A

`He`

B

`Ne`

C

`Ar`

D

Both (1) and (2)

Text Solution

Verified by Experts

The correct Answer is:
4
In helium `(1s^(2))` ,K shell of electrons is full while in neon `(1s^(2)2s^(2)2p^(6))`, both `K` and `L` shells are electrons are full. In other noble gases inner shells are full but valence shell is not full though `s` and `p` subshells of the valence shell are full.
All the noble gases except He have a 'closed' eight-electron outer subshell configuration `(ns^(2) np^(6))`.
