WebProperties of Simple Covalent Molecules. Simple covalent molecules have low melting and boiling points. They are also insoluble in water and are considered poor conductors of electricity since they cannot carry a charge (they are neutral). Common examples of simple covalent molecules include CO 2, O 2, and NH 4. 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.
