Cscl atomic packing factor
WebThe simple cubic (SC) unit cell can be imagined as a cube with an atom on each corner. This unit cell is the simplest for people to understand, although it rarely occurs in nature due to its low packing. SC has 1 atom per unit cell, lattice constant a = 2r, Coordination Number CN = 6, and atomic packing factor APF = 52%.

It is a dimensionless quantity and always less than unity. In atomic systems, by convention, the APF is determined by assuming that atoms are rigid spheres. The radius of the spheres is taken to be the maximum value such that the atoms do not overlap. For one-component crystals (those that contain only o… fb4kmaryland.org
