List of network covalent solids
WebCovalent network solids include crystals of diamond, silicon, some other nonmetals, and some covalent compounds such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds. The atoms in these solids are held together by a network of covalent bonds, as shown in Figure 4. WebThese are also known as network solids as they are formed by an intense network of covalent bonds present in their adjacent atoms forming the solid. The constituent atoms/elements are neutral atoms and can be the same as in diamond (all atoms are of carbon joined together by covalent bonds) or can be different like in silicon carbide …
