Question
Assign reason for each of the following:
Noble gases are mostly chemically inert.
Solution
Genral electronic configuration of noble gas is ns2 np6. Thus having stable coniguration.
Noble gases are mostly chemically inert due to the following reasons:
(i) Atoms of the noble gases have stable closed shell electronic configuration.
(ii) Noble gases have exceptionally high ionisation energies.
(iii) Noble gases have very low electron affinities.
