Density of cesium

Caesium (IUPAC spelling ) (or cesium in American English) is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium. It is WebBased on crystal structure, calculate the theoretical density for Cesium chloride (CSCT What metallic lattice structure does CsCl appear to be analogous to - - Please draw the CsCl structure, and shade the (001) plane.
