Give scientific reasons Inert gases exist in the form of free atoms.

1.	Give scientific reasons Inert gases exist in the form of free atoms.
Answer» i. Formation of molecules is based on the electronic configuration of the combining elements. ii. In the case of inert gases, all the shells, including the outermost shell, are completely filled. iii. They have stable electronic configuration with complete duplet (in case of He) or complete octet (in case of Ne, Ar, etc). iv. Due to this stable electronic configuration, atoms of these elements do not lose, gain or share electrons with other atoms. Hence, inert gases exist in the form of free atoms.

i. Formation of molecules is based on the electronic configuration of the combining elements.

ii. In the case of inert gases, all the shells, including the outermost shell, are completely filled.

iii. They have stable electronic configuration with complete duplet (in case of He) or complete octet (in case of Ne, Ar, etc).

iv. Due to this stable electronic configuration, atoms of these elements do not lose, gain or share electrons with other atoms.

Hence, inert gases exist in the form of free atoms.
