3. Show that in an ideal hexagonal-close-packed (hcp) structure, where the atomic
spheres touch each other, the ratio c/a is given by
:-()*
( 8 \ 1/2

4 The packing ratio is defined as the fraction of the total volume of the cell that is
filled by atoms. Determine the maximum values of this ratio for equal spheres
located at the points of simple-cubic, body-centered-cubic, and face-centered-cubic
crystals.

- 1. For a simple cubic crystalline structure of lattice constant a = 0.4 nm a. b. C. How many atoms are there per unit volume? (Hint: An easy way to proceed is to calculate the volume of the unit cell and the number of atoms per unit cell. Although there are eight atoms involved in any given unit cell, each atom in the simple cubic structure is part of eight different cells, one corner of each. Thus, there are 8 atoms times 1/8 atom per corner or 1 atom per unit cell.) How many atoms per unit area are there in the (100) plane? The (110) plane? The (111) plane?
