WebWhen metal atoms are arranged with spheres in one layer directly above or below spheres in another layer, the lattice structure is called simple cubic. Note that the spheres are in contact. In a simple cubic structure, the spheres are not packed as closely as they could be, and they only “fill” about 52% of the volume of the container. WebThe underlying metal is a crystal, meaning its atoms have a certain ordered structure in space, with the atoms well bonded with each other. The native oxide, formed by reaction with oxygen or water in air, is amorphous, meaning its atoms are randomly distributed, and usually thin (4 nm or 0.000004 millimeters).
