Ionic bonds tend to have low melting points

Web15 nov. 2024 · Intermolecular forces are weaker than ionic or covalent bonds, so molecular solids are relatively soft and flexible. This also means they tend to have low melting points. They do not conduct electricity because electrons are localized within individual molecules. Polar molecular solids, like sugar, will be soluble in water. WebActivity 1.
