Estimate the length of the cubic unit cell edge and and use this to calculate the density of CsCl (Figure) from the ionic radii of cesium, 1.81A, and chloride, 1.64A. (Hint: Ions in CsCl touch along the body diagonal, a vector running from one corner of a cube through the body center to the opposite corner. Using trigonometry it can be shown that the body diagonal of a cube is 3 times longer than the edge.) The density of CsCl is g/cm3 CsCl structure
