摘　　要：In the presented model the wave function describing the electron is a superposition of contributions from individual components of the system, in the case of metals -- lattice ions and in this sense refers not to a single electron, but rather to the system as a whole. An unconventional approach to the Schrtdinger equation can provide a simple analytical relationship between the total energy of the electron and the wave number. This expression can directly determine the basic parameters such as Fermi radius, the screening radius or work function and also produce a graphical interpretation of the Fermi surface.In the presented model the wave function describing the electron is a superposition of contributions from individual components of the system, in the case of metals -- lattice ions and in this sense refers not to a single electron, but rather to the system as a whole.
