Problem: The memory metal, nitinol, is an alloy of nickel and titanium. It is called a  memory metal because after being deformed, a piece of nitinol wire will return to its original shape. The structure of nitinol consists of a simple cubic array of Ni atoms and an inner penetrating simple cubic array of Ti atoms. In the extended lattice, a Ti atom is found at the center of a cube of Ni atoms; the reverse is also true. What is the empirical formula of nitinol?
