Bohr model - Wikipedia What is the difference between Rutherford and Bohr model of the atom 4. He gave his theory of the structure of the atom in 1911 that stated that the majority of the atom's mass is located in a compact, positively charged area in the center of the atom. The Bohr model was proposed in 1922, while the Rutherford model was in 1913. The model also proposed electronic configuration, which explains the arrangement of electrons in circular orbits designated as K, L, M, N, etc. This is the difference between Bohr and Rutherford Model. Bohrs model was proposed by Niels Bohr in 1922 to explain the structure of the atom. Each orbit is unique in its energy and size. In the Bohr model, each orbit may contain more than one electron, and in the Rutherford model . This concept contradicts the atomic model that was later proposed by Neils Bohr.
