A '''crystal''' is a substance in which the constituent atoms are arranged in a consistent, repetitive, and therefore orderly pattern. Crystals are extremely common, forming the basis for many [[rock|rocks]] and [[mineral|minerals]], and playing a large part in the [[biology|biological processes]] of many organisms.
