WebFigure 10.37 The entities of a solid phase may be arranged in a regular, repeating pattern (crystalline solids) or randomly (amorphous). Metals and ionic compounds typically form ordered, crystalline solids. Substances that consist of large molecules, or a mixture of molecules whose movements are more restricted, often form amorphous solids. WebThese substances all crystallize in one of four basic structures: simple cubic ( SC ), body-centered cubic ( BCC ), hexagonal closest-packed ( HCP ), and cubic closest-packed ( CCP ).
