1) Compute the percent ionic character of the interatomic bonds for each of the following compounds: TiO2, ZnTe, Csci, InSb, and MgCl2.

2. Calculate the number of vacancies per cubic meter in iron at 850°C. The energy for vacancy formation is 1.08 eV/atom. The density and atomic weight for Fe are 7.65 g/cm3 and 55.85 g/mol, respectively

3. Molybdenum forms a substitutional solid solution with tungsten. Compute the weight percent of molybdenum that must be added to tungsten to yield an alloy that contains 1.0 x 1022 Mo atoms per cubic centimeter. The densities of pure Mo and W are 10.22 and 19.30 g/cm², respectively.

4. A common metal is known to have a cubic unit cell with an edge length of 0.3614 nm and radius 0.128 nm. If this metal has a density of 8.94 gm/cm3 and an atomic weight of 63.55 g/mole, what is the atomic packing factor?

5. Some hypothetical metal has the simple cubic crystal structure shown in Figure 3.3. If its atomic weight is 70.4 g/mol and the atomic radius is 0.126 nm, compute its density.

6. Using atomic weight, crystal structure, and atomic radius data tabulated inside the front cover, compute the theoretical densities of lead, chromium, and copper, , and then compare these values with the measured densities listed in this same table.
