Verified by Experts

(i) For m ation 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 electronic configuration with complete duplet or complete octet.
(iv) Due to their stable electronic configuration, atoms of these elements do not lose, gain or share electrons with other atoms. Hence, inert gases exist in the forms of free atoms.
