Question

Why are Bohr's orbits called Stationary States?

Answer 1

bhor's orbits are called as stationary stats  because as we know that if an object moves in circular path it will lose energy but, according to bhorelectrons which is moving in the circular path does not lose energy.if electrons lose energy they will fall into nucleus and get burnt

Answer 2

Because as we know that if an object moves in circular path it will lose energy but according to bohr the electrons which are moving in circular path doesn't lose energy. If electrons will fall into nucleus and will get burnt
