Question

cation and anion of the twenty elements of the periodic table

Answer 1

Answer:

Electronic configuration is the number of electrons present per shell.

Inert gases have fully filled valence shell and does not react with other atoms to form molecule. 2,8,8 is electronic configuration of inert gas which shows that these gases do not participate in reactions with other elements.

Example:-

(i) Electronic configuration of Argon

Ar(2,8,8)

(ii) Electronic configuration of Neon

Ne(2,8)

This shows that inert gases are quite stable.
