Perovskite is a mineral containing calcium, titanium, and oxygen. The following diagrams represent the unit cell.
a. What is the formula of perovskite?
b. An alternative way of drawing the unit cell of perovskite has calcium at the center of each cubic unit cell. What are the positions of the titanium and oxygen atoms in this representation of the unit cell? Show that the formula for perovskite is the same for both unit cell representations.
c. How many oxygen atoms surround a given Ti atom in each representation of the unit cell?
