<P> In atomic physics , the Rutherford -- Bohr model or Bohr model or Bohr diagram , introduced by Niels Bohr and Ernest Rutherford in 1913 , depicts the atom as a small , positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus -- similar to structure of the Solar System , but with attraction provided by electrostatic forces rather than gravity . After the cubic model ( 1902 ) , the plum - pudding model ( 1904 ) , the Saturnian model ( 1904 ) , and the Rutherford model ( 1911 ) came the Rutherford -- Bohr model or just Bohr model for short ( 1913 ) . The improvement to the Rutherford model is mostly a quantum physical interpretation of it . The model 's key success lay in explaining the Rydberg formula for the spectral emission lines of atomic hydrogen . While the Rydberg formula had been known experimentally , it did not gain a theoretical underpinning until the Bohr model was introduced . Not only did the Bohr model explain the reason for the structure of the Rydberg formula , it also provided a justification for its empirical results in terms of fundamental physical constants . </P>
