WebJul 1, 2024 · Network solids are hard and brittle, with extremely high melting and boiling points. Being composed of atoms rather than ions, they do not conduct electricity in any state. Figure \(\PageIndex{3}\): Diamond is a network solid and consists of carbon atoms covalently bonded to one another in a repeating three-dimensional pattern.
