Many covalent compounds are flexible or gaseous and are not water soluble. Metallic compounds contain freely floating electrons which allow them to conduct electricity and heat well.

Web1 sep. 2024 · Properties of Covalent Compounds . Most covalent compounds have relatively low melting points and boiling points. While the ions in an ionic compound are strongly attracted to each other, covalent bonds create molecules that can separate from each other when a lower amount of energy is added to them. Therefore, molecular compounds … WebIonic solids tend to have high melting points and are rather hard. Molecular solids are held together by relatively weak forces, such as dipole–dipole interactions, hydrogen bonds, and London dispersion forces. As a result, they tend to be rather soft and have low melting points, which depend on their molecular structure.
