Diamond is a type covalent network solids
WebAs you may have found in answering the previous question, there is a lot of overlap in properties among the four types of solids. For example, platinum (a metallic solid) has a higher melting point than several of the network covalent solids, but the majority of metallic solids have a much lower melting point than network A network solid or covalent network solid (also called atomic crystalline solids or giant covalent structures) is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material. In a network solid there are no individual molecules, and the entire crystal or amorphous solid may be considered a macromolecule. Formulas for network solids, like those for ionic compounds, are simple ratios of the component …

WebJul 29, 2024 · This type of solid is characterized by an irregular bonding pattern. Amorphous solids may be soft and rubbery when they are formed by long molecules, tangled together and held by intermolecular forces. Glassy solids are hard and brittle, formed by atoms irregularly joined by covalent bonds. Examples: Plastic, glass. WebApr 9, 2024 · Covalent solids: A covalent solid consists of atoms at the lattice points of the crystal, with each atom being covalently bonded to its nearest neighbor atoms. The covalently bonded network is threedimensional and contains a very large number of atoms. Covalent solids are hard and brittle, with extremely high melting and boiling points.
