(3) Consider the elements neon and radon. Both are gases at room temperature (298 K) but neon has a
boiling point at 27.1 K and radon has a boiling point of 211.5 K. What is the only type of intermolecular
force observed between atoms of these elements? Why is radon observed to have a higher boiling point
than neon?
