The Bohr model, devised by Niels Bohr, depicts the atom as a small, positively charged nucleus surrounded by    electrons that travel in circular orbits around the nucleus—similar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity. This was an improvement on the earlier plum-pudding model  (1900) and the Rutherford model, the solar system model (1911). Since the Bohr model is a quantum physics-based modification of the Rutherford model, many sources combine the two, referring to the Rutherford–Bohr model.

The Difference Between each Atomic Models

Thomson Model (Plum Pudding) 

Atoms are solid which is slightly positive with embedded negatively charge electrons.

Rutherford Model (Solar System Model) 

The Atom is primarily hollow, with the nucleus in the center and electrons orbiting around the nucleus much like planets like orbiting around the sun.

 Bohr Model 

The Atom is primarily hollow, with the nucleus in the center and electrons orbiting around the nucleus much like planets like orbiting around the sun.  Unlike the Rutherford model, Bohr's model accounts for the wave nature of the electron.  The only possible orbitals are orbitals that multipuls of the wavelength. In the diagram below is the visualization of hydrogen atom.  The Bohr model successful predicted the wavelengths of the hydrogen atom, but failed to predict the wavelengths of the atoms.
