WebAnd scrutinize they did. Niels Bohr (Fig. 6) noticed a problem with Rutherford’s idea: there was nothing keeping the orbit-ing electrons from spiraling into the nucleus of the atom, causing the whole thing to collapse! Bohr modified Rutherford’s basic model by proposing that electrons had set energy levels (Fig. 7). This is the model of the In atomic physics, the Bohr model or Rutherford–Bohr model of the atom, presented by Niels Bohr and Ernest Rutherford in 1913, consists of a small, dense nucleus surrounded by orbiting electrons.
