1. Draw a unit cell for BCC crystal structure and identify one of the most densely packed planes. 2. Chromium has a BCC crystal structure, an atomic radius of 0.125 nm, and an atomic weight of 51.99 g/mol. Compute its density. 3. Derive linear density expression for BCC (111) direction in terms of the atomic radius R. 4. Derive planar density expression for BCC (110) plane in terms of the atomic radius R. 5. List the point coordinates for all atoms that are associated with the FCC unit cell
