When covalent bonds link long chains of atoms in large molecules, however ( as in polymers such as nylon ), or when covalent bonds extend in networks though solids that are not composed of discrete molecules ( such as diamond or quartz or the silicate minerals in many types of rock ) then the structures that result may be both strong and tough, at least in the direction oriented correctly with networks of covalent bonds.
