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 to the BCC lattice structure shown in Figure P2.12
