Question

Which of the following is NOT one of the postulates in the Bohr Model of the Atom?
Only certain orbits are stable, non-radiating, and have fixed energies.
The "allowed" orbits are ones in which the electron's orbital angular momentum in an integer multiple of h/2ππ.
The radius of each "allowed" electron orbit is an integer multiple of the Bohr Radius (a₀).
Atoms emit radiation (light) when the electron makes a transition from a higher energy state to a lower energy state.
The electron moves in circular orbits about the nucleus.

Answer 1

Option 1 is not correct

because all orbit are stable and have fixed energy and it is electron which become unstable if it get energy from somewhere
