Write any three postulates of Bohr's model for hydrogen atom.

Explanation

Postulates of bohr's theory.
Electron revolve round the nucleus in certain orbits of definite energy.
The quantum mechanically allowed orbits are those for which the angular momentum of the morning electron is an integral multiple of quantity `h/(2pi)`
Energy is emitted of Absorbed only when an electron jumps from one orbit to another. When an electron jumps from higher energy to loiner energy the energy difference is emitted in form Cf Radiation.
`E_(2)-E_(1)=DeltaE=hv`
