According to the Bohr model of the atom, the electrons in the atom are in strictly defined orbits, which correspond to the energy levels. Being on them, electrons do not emit, despite the fact that they are moving with acceleration.
When an electron enters an orbit with a lower energy level, the atom emits energy, and when it moves to a more energetic orbit, it absorbs.
