Bonjour!
The main postulates of Bohr’s model for hydrogen atom are as follows :
(i) The electrons in the hydrogen atom revolve around the nucleus in a circular paths of fixed radius and energy called orbits or allowed energy states.
(ii) An electron do not radiate energy if it stayed in one orbit and therefore do not fall into the nucleus.
(iii) An electron moves from a lower energy state to higher energy state after absorbing energy but energy is emitted when electron moves from the higher energy state to lower energy state.
Hope this helps...:)
