11. a) Determine which planes in an fcc structure have the highest density of atoms.
b) Evaluate this density in atoms/cm² for Cu.
12. Repeat Problem 11 for Fe, which has a bcc structure.
13. Show that the maximum packing ratio in the diamond structure is n/3/16. [Hint:
The structure may be viewed as two interpenetrating fcc lattices, arranged such
that each atom is surrounded by four other atoms, forming a regular tetrahedron.]
The angles between the tetrahedral bonds of diamond are the same as the angles between the diagonal of a cube.Use elementary analysis to find the value of angle.
