Expert Answer
Solids are classified as crystalline and amorphous. Crystalline solids have ions, atom or molecules arranged in an orderly array and the elementary particles have a fixed site/place. The fundamental difference between single crystal and amorphous solids is the length scale over which the atoms are related to one another by translational symmetry ('periodicity' or 'long-range order'). Crystals have infinite periodicity and amorphous solids (and liquids) have no long-range order.
