Schematic diagram Rutherford's atom: electrons in green and nucleus in red. The atomic nucleus shown expanded more than 10,000 times its size relative to the atom; electrons have no measurable diameter. 3D animation of an atom incorporating the Rutherford model.
The prevailing model of atomic structure before Rutherford's experiments was devised by J. J. Thomson. [1]: 123 Thomson had discovered the electron through his work on cathode rays [2] and proposed that they existed within atoms, and an electric current is electrons hopping from one atom to an adjacent one in a series.
English: Model of the atom by Ernest Rutherford. He proposed a nucleus with protons and electrons spinning around. He proposed a nucleus with protons and electrons spinning around. Work done by David Marin with the scientific supervision of José Carlos Sánchez Muñoz, a chemist at the School of Engineering of Seville .
English: Basic diagram (rutherford ) of the atomic planetary model (nitrogen): electrons in green and nucleus in red. Deutsch: Atommodell nach Rutherford für Stickstoff, Elektronen: grün, Atomkern: rot
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.

A schematic of the nucleus of an atom indicating β − radiation, the emission of a fast electron from the nucleus (the accompanying antineutrino is omitted). In the Rutherford model for the nucleus, a red sphere was a proton with positive charge, and a blue sphere was a proton tightly bound to an electron, with no net charge.
But Dr. Molly Rutherford, an addiction specialist based in La Grange and the president of the Kentucky chapter of the American Society of Addiction Medicine, said that when she sought help for addicts, she found that many counselors refused to treat her patients who were on Suboxone.
