Arrangement of the Atoms Metals are made up of very large structures of atoms that are stabilized by strong forces. Two atomic arrangements are commonly exhibited in metals: In a 12-co-ordinated array, the atoms in the metallic structure are closely packed and they are in contact with 12 neighboring atoms. On the other hand, an…
