In the LiCl structure shown in Figure 9.21, the chloride ions form a face-centered cubic unit cell 0.513 nm on an edge. The ionic radius of Cl - is 0.181 nm. (a) Along a cell edge, how much space is between the Cl - ions? (b) Would an Na + ion ( r = 0.095 nm ) fit into this space? a K + ion ( r = 0.133 nm ) ?
