Question

What is the electronic configuration of inert gases?

Answer 1

Electronic configuration: The arrangement of electrons into the orbitals of an atom using some fundamental principle is called its electronic configuration.

Inert gases or noble gases:

• The inert gases are also called noble gases which belong to ${18}^{th}$ group of the periodic table.
• Helium, Neon, Argon, Krypton, Xenon, and Radon are inert gases.
• The general electronic configuration of inert gas is $n{s}^{2}n{p}^6$ where $‘n’$ is subshell or energy level and $2,6$ denotes the number of electrons.
• There is an exception for helium here, its electronic configuration is $1s^2$.

Hence, the electronic configuration of inert gases is $n{s}^{2}n{p}^6$.
