Do molecular solids have covalent bonds

WebA. Molecular solids generally have lower melting points than covalent solids. B. Metallic solids exhibit a wide range of melting points because metallic bonds cover a wide range of bond strength. C. The metallic solid can be viewed as positive ions closely packed in a sea of valence electrons. D. WebSummary. The major types of solids are ionic, molecular, covalent, and metallic. Ionic solids consist of positively and negatively charged ions held together by electrostatic forces; the strength of the bonding is reflected in the lattice energy. Ionic solids tend to have high melting points and are rather hard.
