which electronic level would allow hydrogen to absorb a photon but not to emit a photon?

ground state of hydrogen atom,i.e(1s)

Approved

in any energy level if  electron absorbes a photon of energy equal to energy of electron in that level  then electron is ejected from atom and no photon is emmited....

it is its ground  state

Which electronic level would allow the hydrogen atom to absorb a photon but not to emit a photoelectron -1s,2s,2p,3s and why
