Web4 atoms. To calculate the number of atoms in the unit cell, multiply the number of atoms on vertices times the fraction of each atom that is within the unit cell. In a cubic unit cell, corners are 1/8 of an atom, edges are 1/4 of an atom, and faces are 1/2 of an atom. An atom in the center is fully in the unit cell and counts as a whole atom. WebFCC unit cells consist of four atoms, eight eighths at the corners and six halves in the faces.
