- pls answer 11,12e. Notice that the face atom and the corner atoms along the diagonal all touch. Solve for the length of the diagonal in terms of "r" the radius of one atom. Answer: f. Since question 3d and 3e express the length of the diagonal when the side is "a" set them equal and solve for "a", the side of length of a face- centered unit cube. Answer: g. Find the total volume of the atoms in the face-centered unit cell expressed in terms of r. Use commor equations to find the volume of atoms in the unit cell. To do this, take the volume of a sphere in terms of "r" and multiply it by the total number of atoms represented in the unit cell. Answer:Exercise 1: Unit cell dimensions For a crystal with a cubic unit cell, a Bragg reflection for the (100) plane occurs at 20 = 11.26 ⁰. Using Cu Ka = 1.5418 Å as the wavelength (2), calculate the unit cell dimension "a" for this crystal.
