Vedclass · Answer

(A) The boiling point of noble gases increases down the group due to an increase in the magnitude of van der Waals forces as the atomic size increases. Helium $(He)$ has the smallest atomic size and the weakest interatomic van der Waals forces among all noble gases. Therefore,Helium $(He)$ has the lowest boiling point $(4.2 \ K)$.
