Covalent-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.


The different types of solid are ionic solids, metallic solids, network atomic solids, atomic solids, molecular solids, and amorphous solids. So, there are 6 main types.
