The crisscross method uses the oxidation state (valence) of each element or ion. In this example, aluminum (Al) has an oxidation number of 3+. Nitrogen has an oxidation number of 3-. So, there really is no crisscross, because they are both the same, and they would combine to make aluminum nitride, AlN. If, however, you had aluminum, and nitrate ion (NO3^-), the crisscross would be to make the Al subscript a 1 and the NO3- subscript 3 to give Al(NO3)3.

The criss-cross method is a technique used to determine the chemical formula of ionic compounds like sodium chloride. It involves swapping the numerical charges of the elements to create a balanced formula. For sodium chloride, the sodium ion (Na+) has a charge of +1, and the chloride ion (Cl-) has a charge of -1, so the formula becomes NaCl.
