Melting and boiling points depends on _?

Explanation

Melting and boiling points of substances depend on various factors, and one of the factors that play a role is the number of electrons. Electrons are negatively charged subatomic particles that surround the nucleus of an atom. In an atom or molecule, the arrangement of electrons and their energy levels influence the strength of intermolecular forces between particles.Substances with a larger number of electrons generally have stronger van der Waals forces (London dispersion forces) between molecules. These forces arise due to temporary fluctuations in electron distributions, resulting in temporary dipoles. More electrons mean larger temporary dipoles and stronger intermolecular forces, leading to higher melting and boiling points.
