Summary Introduction

To give:

The electron configuration of neon and argon and also give the reason why they are inert elements.

Introduction:

Neon and argon are included in the group of noble gases. Noble gases contain low reactivity because they have closed-shell electron configurations. This makes them inert elements.

The method in which electrons of an atom are arranged in atomic shells is called electronic configuration. Every atomic shell consists of a particular number of atoms. The atomic shells are named as K, L, M, N and so on.
