WebEach face-centered atom is shared by two surround unit cells. Hence, the number of face centered atoms in unit cell, =1/2 x 6 =3 atoms. Therefore, total number of atoms in one unit cell = 1 + 3 = 4 atoms. (ii) Coordination Number In this case, there are eight atoms at the eight corners of the unit cell and 6 atom at the center of the six faces. Web• Rare due to poor packing (only Po [84] has this structure) • Close-packed directions are cube edges.
