1s as hydrogen has only 1 shell to be filled so it can take one electron but it will be difficult or impossible to emmit because of strong force of attraction by nucleus

1s because its the only shell to be filled also strong nucleus force acts on it so it can''t emit photon

Dear Abhisekh,

we know the energy of electron goes on to become more negative as it reaches 1st level energy.
the energy is least at the 1st electronic level and most negative at which the atom can only absorb energy or photons but cannot emit since its in the stable state.emission requires a more lower electronic level to be present so that the electron can jump to it after emtting energy or photons.HENCE,the 1st electronic level would allow the hydrogen atom to absorb a photon but not to emit it.(ANS)

Regards.
Akash
