1. The volume density of atoms for a bcc lattice is 5 x 10^26 m^-3. Assume that the atoms are hard spheres with each atom touching its nearest neighbors. Determine the lattice constant and effective radius of the atom. 2. The lattice constant of a body centered cubic unit cell is a=4.85 °A. Determine the volume density of atoms. (Hints: Volume density=number of unit cell atoms/unit cell volume). 3. Determine volume density of germanium atoms in germanium semiconductor. The lattice constant of germanium is a=6.66°A.
