WebAug 1, 2024 · Like other answers have already pointed out, metals don’t have actual free electrons. In the cartoon this is given by the grey region. If electrons have enough energy to be in the grey region, they’re free. In individual independent atoms (gaseous state), the energy levels below a certain energy are discrete. WebIn the free electron model four main assumptions are taken into account: Free electron approximation: The interaction between the ions and the valence electrons is mostly neglected, except in boundary conditions. The ions only keep the charge neutrality in the metal. Unlike in the Drude model, the ions are not necessarily the source of collisions.
