WebCovalent-network (also called atomic) solids—Made up of atoms connected by covalent bonds; the intermolecular forces are covalent bonds as well. Characterized as being very hard with very high melting points and being poor conductors. Examples of this type of solid are diamond and graphite, and the fullerenes. WebDiamond and Graphite: Two Allotropes of CarbonThese two allotropes of carbon are covalent network solids which differ in the bonding geometry of the carbon atoms. In …
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 (SiC ... 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).

WebNov 2, 2024 · Diamond is an example of a network covalent solid. Because the outer electron shell of each atom contains an electron, diamonds are classified as an ionic solid. When an electron is stimulated, it generates a negative charge in the diamond. The negative charge of an electron forms covalent bonds between the carbon atoms. Because … WebBecause covalent bonds are relatively strong, covalent network solids are typically characterized by hardness, strength, and high melting points. For example, diamond is …
