Bohr did not make the atomic model; he modified Rutherford's. Rutherford had found that the atom consisted of a dense, positively charged center surrounded by negatively charged electrons (Google 'Rutherford gold foil experiment'). Bohr's model added that the electrons move around the nucleus in certain circular orbits, and that each orbit had a certain level of energy that increased the further the electron was from the nucleus.
Features: dense, positive-charged nucleus negatively charged electrons that orbit the nucleus at specific levels
The Bohr model has rings circling around an atomic symbol like planets around an orbit. The rings have specific numbers of electrons. The frst one has 2, second 8, then 16, 32. He made this model because he disagreed with former models. This is all that I have learned. Hope I helped!
