Given the position of classical physics, it was inconceivable that an electron could not orbit freely at any distance from the nucleus. According to Maxwell's electromagnetic laws, all loads subjected to a certain acceleration emit energy in the form of electromagnetic radiation. In the following list are detailed the theories that contradict the model, according to the previous numbering: Thus, each of the bases of the model was refutable from the perspective of classical physics. When analyzing the spectra obtained from atoms of elements other than hydrogen, it was detected that electrons that were located at the same energy level could contain different energies. The energy released when an electron descends from one orbit to another is emitted in the form of light energy (photon).Īlthough Bohr's atomic model perfectly described the behavior of the hydrogen atom, its postulates were not replicable to other types of elements. It is worth noting that the angular momentum of a particle depends on a compendium of all its magnitudes (speed, mass and distance) with respect to the center of the turn. Only orbits are enabled whose angular momentum of the electron meets certain characteristics. Electrons describe circular orbits around the nucleus, without radiating energy.

The propositions of this model, in broad strokes, are the following: Sommerfeld's atomic model emerges to perfect the shortcomings of Bohr's atomic model. 1.1 Limitations of the Bohr atomic modelĬharacteristics Limitations of the Bohr atomic model.
