Web1- The atomic packing factor (APF) is the fraction of the volume in a crystal structure that is occupied by atoms. The formula for calculating APF is: APF = (number of atoms per unit cell x volume of one atom) / volume of unit cell. The atomic radius is given as 0.115 nm. Therefore, the volume of one atom can be calculated as: Web4. Simple Cubic Again not close packed - primitive or simple cubic cell with atoms only at the corners. # atoms/unit cell = 1.
