suming that the chloride and cesium ions touch along diagonal of the cubic unit

Question

suming that the chloride and cesium ions touch along diagonal of the cubic unit cell, calculate the distance between the centers of adjacent Cs^+ and Cl^- ions in the solid. Compare this value with the expected distance based on the sizes of the ions The ionic radius of Cs^+ is 169 pm, and the ionic radius of Cl^- is 181 pm. What type of solid will each of the following substances form? What type of solid will each of the following substances form? The memory metal, nitinol, is an alloy of nickel and titanium. It is called a memory metal because after being deformed, a
