How many atoms in cubic cells

WebThe face-centred cubic system has lattice points on the faces of the cube, that each gives exactly one-half contribution. In addition to the corner lattice points, giving a total of 4 lattice points per unit cell. For simple cubic, number of atoms per cell = 1. For bcc, number of atoms per cell = 2. For fcc, number of atoms per cell = 4.
