2.9 Describe FCC, BCC, and HCP lattice structures. 2.10 Two hypothetical metals are created with different elements that have the same atomic mass (g/mole) and the same atomic radius. Metal A has a density of 9.50 g/cm3 and metal B has a density of 8.73 g/cm3. If one of these metals has a BCC lattice structure and the other has an FCC lattice structure, identify the structure that corresponds to each of one of them. Justify your answer. 2.12 Referring...
