packing fraction of a unit cell is drfined as the fraction of the total volume of the unit cell occupied by the atom(s). P.E=("Volume of the atoms(s) present in a unit cell")/("Volume of unit cell")=(Zxx(4)/(3)pir^(3))/(a^(3)) and % of empty space = 100- P.F.xx100 where Z= effective number of stoms in s cube . r= radius of a an atoms a = edge lenght of the cube Packing fraction in face centered cubic unit cell is :
