The electron in a H atom's stationary state moves in a circle around the nucleus
An atom in a stationary state does not emit electromagnetic radiation as long as it stays in the same state.
When an electron makes a transition from a higher energy stationary state to a lower energy stationary state, then it emits a photon of light.
An atom can take only certain distinct energies E1,E2,E3, etc. These allowed states of constant energy are called the stationary states of atom.
