In atomic physics, the Bohr model or Rutherford–Bohr model, presented by Niels Bohr and Ernest Rutherford in 1913, is a system consisting of a small, dense nucleus surrounded by orbiting electrons—similar to the structure of the Solar System, but with attraction provided by electrostatic forces in place of gravity. D. 3. [ Neon has 8 valence electrons in 2 × de Broglie wavelength ( n = 2 ) orbits. ] These orbits form electron shells or energy levels, which are a way of visualizing the number of electrons in the various shells.
