Covalent network lattice structure
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.
