WebBohr and Bury proposed the following rules for electron distribution. Rule 1: The maximum number of electrons present in a shell is given by the formula 2n 2, where 'n' is the shell number. Rule 2: Each energy level or electron shell is further divided into sub shells. The maximum number of electrons that can be accommodated in each sub shell is 8.

WebThe main three postulates that Neil Bohr gave about the ‘Model of the Hydrogen’ atom are: Atoms have a series of stable orbits within which electrons will exist while not emitting energy; every orbit corresponds to selected energy. Electrons will add a significant jump of one orbit to a different orbit. Planck’s equation gives the ... WebLimitations of Bohr model : 1. It is in violation of the Heisenberg Uncertainty Principle. The Bohr Model considers electrons to have both a known radius and orbit, which is impossible according to Heisenberg. 2. The Bohr Model is very limited in terms of size. Poor spectral predictions are obtained when larger atoms are in question.
