1. elctron in an hydrogen atom revolve around the nucleus in a fixed circular orbit called 'stationary state'
2. electron doesn't loss energy with time to time
3.electron jumps from one stationary state to otherr
4 absorbtion of energy takes place when electrons jumps from lower stationary state to higher
5.emission of energy takes place when e- jumps frm higher stationary state to lower
6. the total transision of energy is given as  Δ e= e2-e1
                                                  where e2 is final orbital energy and e1 in initial orbital energy
7. the frequency of the radiation is given as nue = hc

only certain special orbits known as discrete orbits of electrons are allowed inside the atom

while revolving the electrons do not radiate energy

these shells are called energy levels
