2. Body-Centered Unit Cell a. Below is a body centered unit cell, write the letter "a" along the edge length. Calculate the length of the diagonal if all sides are "a". The dotted line refers to the diagonal of the cubes body. Use the Pythagorean relationship c = a+ b: Answer: b. Notice that the center atom and the two corner atoms along a diagonal all touch. What is the length of the diagonal in terms of "r" the radius of the atom? Answer: T U a c. Since question 2d and 2e express the length of the diagonal when the side is “a" set them equal and solve for "a", the side of length of a body centered unit cube. Answer:
