Vedclass · Answer

(D) Helium $(He)$ has the lowest boiling point $(4.2 \ K)$ among all known substances. This is because helium atoms are very small and have a very stable electronic configuration $(1s^2)$. Due to this,the interatomic forces of attraction,known as van der Waals forces,are extremely weak. These weak forces are easily overcome by thermal energy,resulting in a very low boiling point.
