WebSolution. First Postulate: Electron revolves round the nucleus in discrete circular orbits called stationary orbits without emission of radiant energy. These orbits are called stable … WebAccording to Bohr’s Atomic model, the number of electrons that an orbit or shell can hold can be calculated using the formula: 2n2. Note- ‘n’ is the number of the orbit or shell. For K-shell n=1, for L-shell n=2, for M-shell n=3, and so on. The K-shell can hold a maximum of 2 electrons, the L-shell can hold a maximum of 8 electrons, and ...

The following are the chief postulates explained by the Neils Bohr atomic theory. The model shows that the electrons in atoms are in orbits of different energy levels around the core (like the planets circling the sun).
