Positive and negative aspects of the Bohr Model of the Atom

1st positive aspect of the Bohr Model of the atom

1) The Bohr model works best for simple one electron atoms like He and H. It gives a clear picture as to how electrons are arranged in an atom.

2nd positive aspect of the Bohr model of the atom

2) It introduced the idea that electrons have specific energy levels. The model is closely linked to the arrangement of the periodic table, each period represents how electrons fill the energy levels.

3rd positive aspect of the Bohr model of the atom

3) It accounted for atomic stability by explaining that e- in their lowest energy state (the ground state) cannot lose more energy and remain stable indefinitely in this state.

4th positive aspect of The Bohr model of the atom

4) Bohr linked the atomic structure to quantum theory.

1st negative aspect of the Bohr model of the atom

1) The Bohr model does not work for complex atoms with more than one electron. It only accurately describes the hydrogen atom.

2nd negative aspect of the Bohr model of the atom

2) It does not align with quantum mechanics, electrons are not like tiny planets rather they behave more like clouds of probability. Electrons move around in unpredictable ways.

3rd negative aspect of the Bohr model of the atom

3) The model does not properly explain the movement of electrons in the orbit. The model assumes electrons move in fixed circular orbits, however modern quantum mechanics implies that electrons exist in regions called orbitals not in fixed paths.
