WebThe Structures of Metals. ... The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size. Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1 ... WebMetals are crystalline when in the solid form. The crystal structure of a solid metal refers to the internal structure or arrangement of the atoms in an ordered, repeating, three dimensional pattern. Normal metallic objects are polycrystalline, which means they consist of an aggregate of many very small crystals. These crystals are called grains.
