GENERAL KNOWLEDGE

Detailed explanation-1: -Among the noble gases, Xe has the highest boiling point.

Detailed explanation-2: -Argon will have the higher boiling point because it has a larger molar mass than helium. As the molar mass of an element increases, the boiling point increases.

Detailed explanation-3: -Thus the boiling point increases down the group of noble gases. Also, Xenon has larger mass than helium, neon and hydrogen molecules. Since the atomic size is more, the valence electrons are loosely held with the nucleus. So we can conclude from the above points that xenon has the highest boiling point.
