WebIn the previous section, we identified that unit cells were the simplest repeating unit of a crystalline solid and examined the most basic unit cell, the primitive cubic unit cell. In this section, we continue by looking at two other unit cell types, the body-centered cubic and the face-centered cubic unit cells. Web1. The body-centered cubic unit cell has atoms at each of the eight corners of a cube (like the cubic unit cell) plus one atom in the center of the cube. 2. Each of the corner atoms is …
