3. Determine the diameter of an atom, in terms of r, that fits inside the simple cubic structure. Take r to be the radius of the corner atoms. 4. Lithium bromide crystalizes as shown (right). If the density of LiBr is 3.464 g/mL, calculate the Li-Br distance in the crystal structure. 5. The structure below shows anions (dark circles) in a simple cubic array with cations (white circles) in alternating body centers. One unit cell is shown. Complete the following table for one unit cell to determine the ratio of cations to anions. Cation Anion Corners Faces Edges Internal TOTAL ION PER CELL 6. Taking one of the corners to be the origin, give the lattice points for the face centered cu € unit cell expressed as fractions of the unit cell dimensions (x, y, z).
