Answer 1

It is possible for atoms to stay in their free state only when they have a stable configuration.

Double configuration is a form of stable configuration.

Double configuration can happen when two electrons are present on the valence shell of an atom.

Atoms of Helium gas show this type of configuration.

Answer 2

it is possible for atom to stay in their free state only when they have a stable configuration double configuration is, form a stable configuration
