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.

(a) Differentiate between Face- Centered Cubic (FCC) and Body-Centered Cubic (BCC) crystal structures. Why FCC metals are more ductile than BCC metals? 5 marks) (ii) show the relationship between the unit cell edge length, a, and the atomic radius, R, for a BCC crystal. Iron has a BCC crystal structure, an atomic radius of 0.124 nm, and atomic weight of 55.85 g/mol. Calculate its theoretical density Given: Avogardo's Number is 6.02 x 105 atoms/mol (5 marks) Figure 1 Determine the...
5 The atomic weight and atomic radius for a hypothetical BCC metal are 43.1 g/mol and 0.122 nm respectively. Determine its density. 6 Calculate the radius of a iridium atom, given that Ir has a FCC crystal structure, a density of 22.4 g/cm^3, and an atomic weight of 192.2 g/mol.
--Given Values-- Atomic Radius (nm) = 0.116 FCC Metal = Gold BCC Metal: = Sodium Temperature ( C ) = 1017 Metal A = Tin Equilibrium Number of Vacancies (m-3) = 6.02E+23 Temperature for Metal A = 369 Metal B = Gallium 1) If the atomic radius of a metal is the value shown above and it has the face-centered cubic crystal structure, calculate the volume of its unit cell in nm3?
