Why was a change in the Bohr Model of atom required? Due to which important development(s), concept of movement of an electron in an orbit was replaced by the concept of probability of finding electron in an orbital? What is the name given to the changed model of atom?

In Bohr model, an electron is regarded as a charged particle moving in well defined circular orbits about the nucleus. The wave character of the electron is not considered in Bohr model. Further, an orbit is a clearly defined path and this path can completely be defined only if both the position and the velocity of the electron are known exactly at the same time. This is not possible according to the Heisenberg uncertainty principle.
Bohr model of the hydrogen atom, therefore, not only ignores dual behaviour of matter but also contradicts Heisenberg uncertainty principle.
Thus, to overcome the shortcomings of Bohr’s model, more suitable model of atoms was developed which is consistent with
1. Dual behavior of matter,
2. Heisenberg uncertainty principle
Quantum mechanics is a theoretical science that deals with the study of the motions of the microscopic objects that have both observable wave like and particle like properties and is consistent with Heisenberg uncertainty principle.
Due to this important development(s), concept of movement of an electron in an orbit was replaced by the concept of probability of finding electron in an orbital
The name of the changed model of the atom is the Quantum Mechanical model of the atom.
