WebThe sizes of the circular orbits for hydrogen-like atoms are given in terms of their radii by the following expression, in which α0α0 is a constant called the Bohr radius, with a value of 5.292 × 10 −11 m: WebBohr's model of atoms: the tiny nucleus with electrons revolving in the concentric orbits. The electrons are bounded to the nucleus by the electrostatic force between them. Unlike the earlier Rutherford model, the orbiting electrons do not continuously radiate energy. The orbits, aka stationary orbits, are stable and discrete with a fixed radius.
