How many atoms are present in a face centred cubic unit cell?

WebFCC FCC has eight comer atoms shared by eight other cell and six face center atoms shared by two cells. Thus the # of atoms per cell is 8x1/8 + 6x1/2=4 atoms per cell for FCC BCC Again eight corner atoms shared by eight cells and 1 center atom fully contained in the unit cell. So the # of atoms per cell for BCC is WebThe face-centred cubic (FCC) has a coordination number of 12. One-eighth of an atom at each of the eight corners i.e 8 × 1 / 8 = 1 atom from the corners. One-half of an atom on each of the six faces i.e 6 × 1 / 2 = 3 atoms from the faces. Hence, there is a total of 4 atoms in a face centred cubic unit cell.
