The simple model for the electronic structure of surfaces of simple metals given in part I is used to investigate three problems: 1. possibility and physical background for systematization of surface energies, 2. anisotropy and 3. temperature dependence of surface energies, dipole barriers, and relative lattice relaxation. It is shown that the surface energies show a characteristic dependence from the density parameter r s and from the valency Z which seems to be most pronounced for valencies one and two. The model is reliable for closed‐packed surfaces up to a value of the surface packing fraction of 0.7. The static electronic part of surface energy considered here yields only a very small temperature dependence.
