Draw the perovskite structure using the chemical formula for the materials by far most commonly associated with the perovskite structure. (Caution: Use proper size ratio between the elements in your sketch) !!!Prove that the total electrostatic bond strength of the bonds reaching an anion from all the surrounding cations should be equal to the charge of the anion in this perovskite structure according to Pauling’s second rule!!!

some oxide superconductors adopt a crystal structure similar to that of perovskite CaTiO3. the unit cell is cubic with a Ti4+ ion in each corner, a Ca2+ ion in the body center and O2- ions ate the midpoint of each edge. (a) if the unit cell edge length is 3.84 A, what is the density of perovskite in g/cm3??
