Unformatted text preview: , ,  and . On top face, we go from one comer to middle of opposite edge. Changing sign right through changes sense of same line in space. Calculate the packing factor of the FCC compound LiP, the ionic radii are 0.068 and 0.133 nm respectively. 5. Volume of Atoms P.F. = Volume of Cell FCC compound, hence 4 of each per cell and 2R. 2r=a 4. j7t (0.0683 + 0.1333) 23(0.068 + 0.133)3 PF= PF=~ Calculate the density of CsCl. Avogadro's number is O.6022x1024, the a.m.u. are Cs = 133 Cl = 35.5. The ionic radii are Cs = O.169nm and Cl- = O.181nm. Recollect that CsCl does ,nQ! have the same crystal structure as NaCl. 6. = 4.24 Mg/m3...
