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.
