In the "classical" model of an atom, with electrons orbiting the nucleus like planets around a star, electrons are travelling in a circle. Electrodynamics show that a charged particle doing so should radiate energy, thus resulting in a smaller radius. As the radius shrunk, the electron should continue to radiate energy until it had lost all its energy and was back into the nucleus -- and do all this in about 10^-11 seconds!!
In addition, the frequency of the light given off should be equal to the frequency of the electron's orbit. As the energy of the electron becomes smaller and the radius shrank, the orbital frequency should get progressively larger. As such, the emission should a range of frequencies, starting low and then getting higher -- much like the frequency produced by a Trombone as the player moves the slide while blowing the whole time. However, emission spectra are, instead, quite discrete in their frequencies.
To solve these problems, Bohr (rather arbitrarily) proposed that electrons did, indeed, orbit the nucleus in circles, but that orbits of certain radii resulted in no radiation be given off. Make this assumption, and the frequencies of hydrogen emission spectra are almost trivial to compute.
The Bohr model of the atom was a planetary model.
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
The modern model of atom is quantic and is different from the Bohr model.
the differences between the modern model of hydrogen and bohr's model is that the modern version is much more advanced in what is known about the model, but bohr's model is very basic
Niels Bohr propose a planetary model for the atomic nucleus.
The Bohr model of the atom was the first to propose that electrons orbit the nucleus in fixed paths or energy levels. This model was proposed by Niels Bohr in 1913, and it helped to explain the stability of atoms and the emission of specific frequencies of light.

The Bohr model of the atom was a planetary model.
The atomic model of Bohr is not a quantum model.
Bohr's model explain the structure of mono electronic system
Neutrons were discovered in 1932, after the model of Bohr.
