In atomic physics, the Bohr model or Rutherford–Bohr model was the first successful model of the atom. Developed from 1911 to 1918 by Niels Bohr and building on Ernest Rutherford 's nuclear model , it supplanted the plum pudding model of J J Thomson only to be replaced by the quantum atomic model in the 1920s.

I created this file to be an SVG alternative to Image:Bohratommodel.png and Image:Bohr model Balmer 32.png. I did not draw the orbitals to scale like the latter diagram because I could not readily find information about the orbitals' radii. For some reason, the "+" on the nucleus is rendering off-centered. The SVG doesn't look like that.
Bohr dropped his work on the Thomson model in favor of Rutherford's nuclear model, developing the Rutherford–Bohr model over the next several years. Eventually Bohr incorporated early ideas of quantum mechanics into the model of the atom, allowing prediction of electronic spectra and concepts of chemistry.
The Bohr model of the chemical bond took into account the Coulomb repulsion - the electrons in the ring are at the maximum distance from each other. [2] Thus, according to this model, the methane molecule is a regular tetrahedron, in which center the carbon nucleus locates, and in the corners - the nucleus of hydrogen. The chemical bond between ...
Rutherford's model, being supported primarily by scattering data unfamiliar to many scientists, did not catch on until Niels Bohr joined Rutherford's lab and developed a new model for the electrons. [54]: 304 Rutherford model predicted that the scattering of alpha particles would be proportional to the square of the atomic charge.
1913 Niels Bohr presents his quantum model of the atom [3] 1913 Robert Millikan measures the fundamental unit of electric charge; 1913 William Henry Bragg and William Lawrence Bragg work out the Bragg condition for strong X-ray reflection; 1914 Ernest Rutherford suggests that the positively charged atomic nucleus contains protons [4]
