WebWe find two types of closest packing in simple metallic crystalline structures: CCP, which we have already encountered, and hexagonal closest packing (HCP) shown in Figure 10.54. Both consist of repeating layers of hexagonally arranged atoms. WebThe immobile cations are arranged as a giant three-dimensional lattice, and the lattice is held together due to attractive interactions between the lattice and delocalized electrons. Metallic bonds are usually described as being nondirectional interactions because the delocalized electrons collectively act as a glue that affects all the metallic cations equally.
