WebFor n atoms in a close-packed structure, there are n octahedral holes. The size of an octahedral hole will depend upon the size of the atoms which are close-packed. Ionic solids and alloys are often viewed as a close-packed arrangement of the larger metal or ion, with the smaller atom or ion occupying the holes. WebThe Hexagonal Close-Packed (HCP) crystal structure is one of the most common ways for atoms to arrange themselves in metals. The HCP crystal structure is based on the Bravais lattice of the same name, with 1 atom per lattice point at each corner of the hexagonal prism, and 3 inside the prism.
