WebCrystal structure changes to accommodate the larger atoms. At even higher T substances changes to liquid and eventually to gas. Liquids and gases do not have an ordered crystal structure and are not minerals. Increase in P pushes atoms closer together. This makes for a more densely packed crystal structure. Examples: WebCrystalline solids are the most common type of solids, whose structure consists of a regular, repeating pattern of atoms or molecules in three dimensions. There are four different types of crystalline solids, all with different properties: ionic, covalent network, metallic and molecular.
