WebPrimitive Cubic Unit Cell; Atoms are only present in the corners of the primordial cubic unit cell. Each atom in the corner is shared by eight neighboring unit cells. Four unit cells are contained within the same layer, and four are contained within the higher (or lower) layer. As a result, each unit cell contains only 1/8th of an atom.

WebA BCC unit cell contains two atoms: one-eighth of an atom at each of the eight corners (8 × 1 8 1 8 = 1 atom from the corners) plus one atom from the center. Any atom in this structure touches four atoms in the layer above it and four atoms in the layer below it. Thus, an atom in a BCC structure has a coordination number of eight.
