Introduction to Wave Mechanical Treatment

The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around the nucleus in certain well-defined circular orbits. But the idea of uncertainty in position and velocity overruled the Bohr's picture of fixed orbits. Thus, the classical mechanics could not describe the behavior of electrons in atoms correctly. Therefore, the scientists started looking for a model, which could incorporate the dual character of matter and uncertainty principle. This resulted in a new approach called Wave Mechanics.
