The ideal perovskite (ABO3) structure consists of AOs closest packed layers (ordered Am cations and O2-anions) with B cations in ¼ of the octahedral holes. What pairs of charges are possible for A and B (there is more than one combination of charges)? For each pair, say which cation will likely sit in the closest packed layers and which will likely sit in the holes. Without specific examples of ions (e.g., Ca, Ti+), base your answer around the fact that...
