Answer:
The postulates of bohr's model of hydrogen atom is
First Postulate: Electron revolves round the nucleus in discrete circular orbits called stationary orbits without emission of radiant energy. These orbits are called stable orbits or non-radiating orbits.
Second Postulate: Electrons revolve around the nucleus only in orbits in which their angular momentum is an integral multiple of h/2π.
Third Postulate: When an electron makes a transition from one of its non-radiating orbits to another of lower energy, a photon is emitted having energy equal to the energy difference between the two states. The frequency of the emitted photon is then given by, v= E i −E f / h.
