Explain why the Bohr model was insufficient and how the quantum model explained this deficiency. How is the electron viewed differently in each model

Answer and Explanation:

Bohr's model of the atom defined the electron as a particle that orbits around the nucleus in only certain orbital levels. As a result, it couldn't readily give account of the energy levels of larger elements with high atomic number.

The quantum model of the atom however, approaches the electron in an atom as not just a particle but a wave, with its distinct quantum number per energy level. It can therefore give the position and speed of an electron simultaneously at any energy level.

I hope this explanation is sufficient.
