WebIn this article we will discuss about the most common crystal structures in metals:- 1. Body Centred Cubic (BCC) Crystal Structure 2. Face Centred Cubic Crystal Structure 3. Hexagonal Close-Packed (HCP) Crystal Structure. Metals are normally crystalline, or rather in solid state, they are almost synonymous to crystalline state. But their crystalline nature is … WebBecause closer packing maximizes the overall attractions between atoms and minimizes the total intermolecular energy, the atoms in most metals pack in this manner. We 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 .
