In terms of intermolecular forces why does HI require more heat energy for melted by than does HCl ?

HI is bigger than hcl hence more van der waals forces

From HCl to HI the boiling point rises. This trend is attributed to the increasing strength of intermolecular van der Waals forces, which correlates with numbers of electrons in the molecules.

HI has more electrons involved compared to HCl, which means the intermolecular forces between HI are stronger, stronger Van der Waals forces or London Forces, therefore more energy required to overcome the intermolecular forces.
