Is there any other difference in the atomic structure of bohr and Rutherford except that of shells?
Rutherford knew the electrons were outside of the nucleus and they were equal in number to the "positiveness" of the nucleus. Rutherford randomly placed the negative electrons outside the nucleus.
Bohr's improvement of the Rutherford model was that Bohr placed the electrons in distinct energy levels. This Bohr model matched the experimental data that Max Planck had determined from his work on the different energies of photons.
If you will search Rutherford and Bohr models of the atom and narrow your search to images, you will find some of the models.
