WebWe know that as we move down the group, the size of the atom increases, and hence the electronegativity of the atom decreases. Thus for group 17 elements, fluorine will be the … WebI've been trying to understand why NaF has the highest melting point among all of the given solids. I thought it would be NaI as it will have the biggest molar mass among them which would mean it has the strongest intermolecular forces. Is it electronegativity difference or molar mass that you look at when analysing intermolecular forces?
