Question

How does Bohr's Model of an atom violates The Heisenburg's Uncertainty Principle?

Answer 1

In Heisenberg uncertainty principle, there is this electron shell that encircles the nucleus. In this electron shell, there is a probability that you can locate the electron but it is not 100% in a particular position because it is moving. In Bohr's model, the electrons have fixed orbitals in which you can locate the exact orbit of the electrons. Bohr's model made simplifications in the analysis of electron and its quantum numbers. Relative to the Heisenberg Uncertainty principle, Bohr's Model is not consistent in it, in a sense that is somewhat violates the uncertainty principle.

Answer 2

an orbit is a clearly defined path and this path can be completely defined only if the position and the velocity of the electron are known exactly at the same time.This is not possible according to H.U.Principle.For viewing an electron high standard equipments using wave nature of light is needed.Getting a part of energy from that incident light makes the electron excited..So at a time we cant find the position and velocity..
