Melting Point Trend for Group 17 (Halogens, F2, Cl2, Br2, I2)

The larger the molecule, the higher the boiling point, because larger molecule = more polarizable = strong London dispersion forces = stronger intermolecular forces = molecules are more attracted to each other = tougher to break molecules apart = more heat needed to melt the solid.
