WebMar 5, 2024 · In the hydrogen atom, in which the nucleus is just a proton, the ratio M / m is about 1836, so that μ = 0.99946m. For heavier hydrogen-like atoms it is closer to m. Notice that the radius depends on n2, so that, for example, the radius of the n = 2 orbit is four times that of the n = 1 orbit. WebThat's why the Bohr model has been replaced by the modern model of the atom. The Bohr model only worked for Hydrogen atoms, and even for hydrogen it left a lot unexplained.
