why are bohr's orbits called stationary states?
a object moving in circular orbit lost energy but according to bohr electrons in orbitsals do not loose energy. if they loose energy then they fall in nucleous and hence atonm is colapse. so electrons do not loose energy thats why these are know as stationary staes or orbitals
Bohr's orbits are called as stationary states because as we know that if an object moves in circular path it will lose energy but, according to bohr electrons which is moving in the circular path does not lose energy.if electrons lose energy they will fall into nucleus and get burnt.
The orbits in which the electrons are allowed to revolve around the nucleus , these orbits have fixed radius also fixed value of energy that’s why these are called allowed energy levels or stationary **states.
** The word stationary means that the energy of the electron moving in particular Orbit is fixed and does not change with time.
