Enthalpy of fusion and enthalpy of vaporisation of Nobel Gasses

Enthalpy of fusion and enthalpy of vaporisation-

The enthalpy of fusion and enthalpy of vaporisation of noble gases are very low . It's due to the presence of the of weak van der waals forces of attraction among the molecules of noble gases. However, the values of these properties increase from He to Rn which may be due to the increase in the magnitude of inter- atomic forces.
