Strategy: Consider the trend in atomic size and its effect on physical properties in Group 18.
Step 1: Physical Parameters As we move down the group from to , atomic size increases and valence electrons are further from the nucleus.
Step 2: Polarizability Increased size leads to higher polarizability, which increases the strength of London dispersion forces. This manifests as higher boiling points and better solubility in water.
