Calculate the predicted boiling point for radioactive radon,Rn,given the boiling points of krypton,Kr, (-152 °C)and xenon,Xe, (-107 °C).

Question

Quizplus · Accepted Answer

The boiling points of the noble gases increase as you move down the group in the periodic table due to increasing van der Waals forces as the atomic size increases. Given that radon (Rn) is below xenon (Xe) and krypton (Kr) in the group, its boiling point would be expected to be higher than that of xenon but follow the trend. The increase from Kr to Xe is 45 °C (from -152 °C to -107 °C). If we apply a similar increase for Xe to Rn, the boiling point of Rn would be higher than -107 °C, making -62 °C a reasonable estimate following the trend.
