Metallic magnesium has a hexagonal close-packed structure and density of 1.74g/cm^3. Assume magnesium atoms to be spheres of radius r. Because magnesium has a close-packed structure, 74.1% of the space is occupied by atoms. Calculate the volume of each atom; then find the atomic radius r. the volume of a sphere is equal to 4π^3/3.

The noble gas argon (atomic weight 39.95 g/mol) can crystalize into a simple hexagonal lattice.The interatomic bond energy as a function of atom separation r is well described a Lennard-Jones type potential: U(r)= (A/r^12)-(B/r^6) where A = 1.57x10-14 J-Å12 and B = 1.02x10-17 J-Å6. Given that the c/a ratio for a close-packed hexagonal structure is 1.63, calculate the density of solid Ar in g/cm3. (Avogadro’s constant = 6.022x1023)

We can estimate the physical density of any material based on the unit cell, the known size of the atoms it encompasses, and their atomic mass. Since density=mass/volume, for the mass in the unit cell we simply need to determine the number of atoms per cell * their mass from the periodic table / Avogadro’s number. For the volume of the unit cell, we just need to determine the lattice parameter of the unit cell (a) following the same rules...
