 Five important points about bohr's model for hydrogen atom 1.    The electron in the hydrogen atom move around nucleus in fixed circular paths called as orbits. These orbits are arranged concentrically around the nucleus 2.   The energy of an electron does not change with time. However, electron will move from lower stationary state to higher stationary state and energy is absorbed by the electron And emitted when electron moves from higher stationary state to lower stationary state.  Energy state does not take place in the continuous manner. 3. Frequency of emission or absorption is given by the following equation:: V= E/H.    'E'   is the difference between higher stationary state and lower stationary state. 4.  Angular momentum of electron is given by the following formula.. MVR=n.h/2π 5.   Electron in the atom of hydrogen move in the fixed orbits whose angular momentum is divided by h/2π
