Diamond extended structure
WebNetwork covalent materials, such as diamond, C, silicon, Si, and silicon dioxide (quartz and sand), SiO 2, have atoms arranged in an extended 3-dimensional lattice of strong, shared electron pair covalent bonds: Network covalent materials are hard, refractory, brittle, usually electrical insulators, and they are not soluble in any solvent. WebAug 31, 2024 · Because strong covalent bonds, rather than London forces or dipole forces, hold the carbon atoms together in this crystal, it takes a great deal of energy to separate them. Accordingly, diamond has an extremely high melting point, 3550°C—much higher than any ionic solid. Diamond is also the hardest substance known.
