question

Using the following ionic radii, find the fractional void volume in (a)CsCl, (b)NaCl, (c)LiCl. Assume that the ions are hard spheres in contact. Ion Radius, \AA Li^+ 0.60 Na^+ 0.95 Cs^+ 1.69 Cl - 1.81 InCsClthe positive ions and the negative ions each comprise a simple cubic lattice. Each ion has eight oppositely charged ions as nearest neighbors. InNaCland LiClthe ions of each sign comprise a face-centered cubic lattice. Each ion has six oppositely charged ions as nearest neighbors.
