Explain Niels Rohr’s atomic model. OR Write the postulates of Bohr’s atomic model. |
|
Answer» The important postulates of Bohr’s atomic model are as follows: 1. The electrons revolving around the atomic nucleus lie in the concentric circular orbits at certain distance from the nucleus. 2. Energy of an electron is constant while it is in a particular orbit. 3. When an electron jumps from an inner orbit to an outer orbit it absorbs specific amount of energy, and when it jumps from an outer orbit to an inner orbit it emits specific amount of energy. 4. The energy emitted or absorbed during these transitions is equal to energy difference between the initial state and the final state of the electron. |
