Knowledge of the type of packing and side length a of the unit cell will allow calculation of the atomic radius, using one of the equations below. You may need to draw the unit cell to determine which formula to use to calculate the atomic radius.

Use what you learned in lab about atoms in cubic structures to answer the following questions about a solid whose crystal structure was found to have atoms "A" in face sites and "B" in the edge and center sites of a cubic unit cell. How many "A"s are there in a unit cell? 3 "A"(s) How many "B"s are there in a unit cell?
