A unit cell of cesium chloride is illustrated in Figure 12.8. The density of the solid is 3.99 g/cm³, and the radius of the Cl⁻ ion is 181 pm. Calculate the radius of the Cs⁺ ion in the center of the cell. (Assume that the Cs⁺ ion touches all of the corner Cl⁻ ions.)

Data given in Figure 12.8

Cl- ions at each cube corner = 1 net Cl- ion in the unit cell. Cl-, radius 181 pm = Cl- lattice and Cs+ in lattice hole
