WebFeb 21, 2024 · Explanation: The more electrons a molecule has, the greater the intermolecular attractions. Also, a larger size increases the London dispersion forces. The increased attraction of the molecules to each other means that more energy is needed to separate them from each other. Hence, the boiling point increases. Answer link WebJul 10, 2015 · Since melting and boiling points tend to increase towards groups 7 and 8, we can safely assume that this optimal average charge is at least greater than + 3, and it is likely higher for the heavier elements since they have significantly higher melting/boiling points.
