Question

Limitations of Bohr's Atomic Model

Answer 1

The Bohr's atomic model has certain shortcomings and limitations. First of all, it does not explain why electrons should be limited to certain orbits. This directly assumes that the electrons have a known radius and orbit. However, this is not entirely true. Ten years later, Heisenberg's uncertainty principle refuted this. Although this atomic model was able to model the behavior of electrons in hydrogen atoms, it was not as accurate when it came to elements with more electrons. This is a model that has trouble explaining the Zeeman effect. This theory gives the wrong value of the angular momentum of the ground state orbit. Because of these limitations, the Bohr atomic model was replaced by quantum theory years later.
