Vedclass · Answer

(C) Noble gases have stable electronic configurations $(ns^2 np^6)$,which results in very high ionization energy and almost zero electron affinity. Due to weak van der Waals forces,they have low boiling points and do not liquefy easily. However,the statement that they do not form any chemical compounds is incorrect,as noble gases like $Xe$ and $Kr$ are known to form compounds with highly electronegative elements like $F$ and $O$.
