WebAtoms in metals are arranged like closely-packed spheres, and two packing patterns are particularly common: body-centered cubic, wherein each metal is surrounded by eight equivalent metals, and face-centered cubic, in which the metals are surrounded by six neighboring atoms. Several metals adopt both structures, depending on the temperature. WebCrystal Structure of Metals: When a metal is melted, metallic atoms detach themselves from other metallic atoms and vibrate rapidly in random directions. For solidification of metal from liquid stage, all that is required it that a sufficient number of atoms may exist in the proper arrangement so that a crystal may grow.
