Imagine a unit cell that consists of corner-centered atoms "A", body-centered atom "B", face-centered atoms "C", and edge-centered atoms "D". This would mean that the total parts of "A" would add to Blank 1 atom(s), the total parts of "B" would add to Blank 2 atom(s), the total parts of "C" would add to Blank 3 atom(s), and the total parts of "D" would add to Blank 4 atom(s).
Assume that a crystal structure is made up of 473 unit cells that all contain corner-centered atoms and body-centered atoms. What is the total theoretical number of atoms for the entire structure?
Using Figure 2 from the lab manual, observe the edge-centered, corner-centered, and face-centered atoms, which are represented by spheres. Match the sphere type with the number of unit cells that share an entire sphere. (For example body-centered would be one, since it is completely contained in one unit cell.)

The structure of solids can be described as if they were
three-dimensional analogs of a piece of wallpaper. Wallpaper has a
regular repeating design that extends from one edge to the other.
Crystals have a similar repeating design, but in this case the
