This long distance before the electron explains how we can get so much conductivity with few free electrons and wave doesn’t channel. Now let us look at the distribution of the electrons. The key is going to be the Pauli Principle. Use the “particle in a box” again to get a one-dimensional version of the energy distributions of the electron.

Recall that the energy levels in a box are
and we know that we can only put two electrons in a state with a given n, one with spin up, one with spin down, according to the Pauli Principle
