Web7.7 CsCl has 8 Cl– at the corners of the unit cell cube, with the Cs+ at the center. r+/ r– = 173/167 =1.04. CaF2 has the same structure in a single cube of F – ions, but only half the cubes contain Ca2+. r+/ r– = 126/119 = 1.06. Both should have coordination number = 12 based on the radius ratios. In crystallography, atomic packing factor (APF), packing efficiency, or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles. 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… eagle islington https://reiningalegal.com
