A monovalent metal has a bcc structure and its lattice parameter is . Calculate its Fermi energy.
For a bcc monovalent metal, the number of atoms per unit cell is 2. The lattice parameter is (a = 1.5 , \text{Å} = 1.5 \times 10^{-10} , \text{m}). The volume of the unit cell is: [ V_\text{cell} = a^3 = (1.5 \times 10^{-10})^3 = 3.375 \times 10^{-30} , \text{m}^3 ] The number density of electrons (n) is the number of electrons per unit volume. For a monovalent metal, there is 1 conduction electron per atom, so: _________ _________ ___ ____ _________ _______ ____ _____ ____ ____ ___ ____.
