(nearest-neighbor distance) and for the body-centered cubic this distance is 3a/2. A body-centered cubic lattice has eight lattice points where a lattice point is defined as a point of intersection of two or more grid lines. Each lattice point, eight in the diagram above, is a âsiteâ for an atom to reside. However, the unit cell above does not contain 8 atoms but only 1. When considering cubic
