Describe Bohr’s model of the atom.



Bohr’s model was based on the limitations of Rutherford’s model 

The model stated that:

  1. Electrons move around Nucleus of an atom in discrete orbits (specific paths). These orbits are called energy levels or shells.
  2. Electrons keep on revolving in the same shell without radiating energy while revolving (there is no loss of energy ).


  • Different energy shells are K shell, L shell, M shell and N shell
