WebC. Minerals and rocks are distinguished by the continuity of the material. Minerals are characterized by continuous arrangement of the constituent atoms, whereas rocks are composed of different minerals and hence are inhomogeneous. This homogeneity is exhibited on the optical, physical and chemical properties of the minerals. WebCrystals are materials that have a repeating arrangement of atoms. Single crystals, like gemstones, have a single grain so the periodic array of atoms is never interrupted. Polycrystals, like metal, have many grains which are usually too small to see.
