Drawbacks of bohr's model class 11

WebApr 5, 2024 · Hint: Bohr proposed his model of an atom and its postulates to overcome the drawbacks of Rutherford’s model and to explain the line spectrum of hydrogen. Bohr's model of an atom mainly tells about the energy levels in the atom. Complete step by step answer: The main postulates of Bohr’s model of an atom are given below: 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.
