Abstract

Is solved the problem of hydrogen. The starting point is a planetary model of the atom and the concept that electrons move in classical elliptical orbits, and that all parameters of its motion (coordinates, momentum, energy, speed, etc.) appear as continuous functions of time. Discrete radiation spectrum of the atom is explained by the resonance condition between the speed with which electrons move in an orbit and the rate of precession. Special attention is paid to the question why Rydberg constant in angular speed is exactly twice less than Borov's speed. Considered again the question of so-called resonance formula. Reached the conclusion that the resonance formula explains at the same time, atomic and molecular spectra. It is note that the physic does not need energy quanta - photons. It is note also that the resonance formula can be a solid foothold in the fight against relativism.
