Buhrs atomic model differed from ruthofords because it explained that

Buhrs atomic model differed from ruthofords because it explained that electrons exist in specified energy levels surrounding the nucleus. This means that, Ruthoford believed that electrons can't do very much. However, Buhrs' model showed that electrons are much more powerful than anyone else believes they can be.

Explanation:

Rutherford's model shows most of an atom mass is in the middle with a positive charge while the negatively charged electrons are outside in a cloud. Bohr improved on his model and explained that the electrons move in certain orbits around the central mass (called the nucleus.)
