Niels Bohr, revised Rutherford’s atomic model and put forth the following suggestions:
Neils Bohr proposed that the electrons possess a specific amount of energy which allows them to revolve around the nucleus. The electrons are confined to these energy levels. While revolving in these discrete orbits, the electrons do not radiate energy. Hence, these orbits are also known as stationary orbits or stationary shells. Smaller the size of the orbit, smaller is its energy.
As we move away from nucleus, the energy of the orbit increases progressively. The transfer of an electron from one orbit to another is always accompanied with absorption or emission of energy. When an electron jumps from a lower energy level to a higher energy level, it absorbs energy. When an electron returns from a higher energy level to a lower energy level, it emits energy.
