Problem 6.14 in book We can look at the band structure of an element to get an idea of how many electrons per atom participate in conduction. We can also determine this number based on the free electron density, the atomic mass, and the mass density of the material. (a) Calculate the free electron density of lithium. The Fermi energy is 4.72 eV. (b) Derive a formula for the number of atoms per unit volume. (c) Calculate the number of atoms per unit volume of lithium (535 kg/m3, 6.9 g/mol) using the formula you derived in part (b). (d) Determine the number of free electrons per lithium atom. (e) What is the electron configuration for Li
