In H-atom ionisation energy is less than 1 eV is for n =4( E 4=-0.85 eV ) on wards. therefore minimum value of n =4

Q. A hydrogen atom in an excited state is ionised by the absorption of radiation with a photon energy of $1 e V$ . What is the minimum value of $n$ for excited state of the atom :-

$1$
