Gold is a dense metal, with a density of 1.93 × 10⁴ kg/m³ at T × 300 K. (a) If gold has exactly one conduction electron per atom, what is its Fermi energy? Compare your result with the measured value in Table 9.4. (b) If the electrons in gold were treated as a classical ideal gas, what would be their mean thermal energy (also at 300 K)? Explain the large discrepancy between your answers in (a) and (b).
