Calculate the classical mean kinetic energy for the electrons in sodium at room temperature. From this, determine their de Broglie wavelength 2. For a classical description to be valid, we must require that λ is much smaller than the mean separation d of the particles. Show that this is not the case, given that the electron density in sodium is 2.65x1028 m³.
