WebBohr improved Rutherford’s model by proposing that electrons traveled about the nucleus in orbits that had specific energy levels. Bohr’s Third postulate overcomes the limitations … WebIn the Bohr model of the atom, the nucleus contains the majority of the mass of the atom in its protons and neutrons. Orbiting the positively-charged core are the negatively charged electrons, which contribute little in terms of mass, but are electrically equivalent to the protons in the nucleus.
