Question

If first excitation potential of a hydrogen-like atom is V electron volt, then the ionization energy of this atom will be, V electron volt, 3 V 4 electron volt, 4 V 3 electron volt, Cannot be calculated by given information

MARKS App · Accepted Answer

First excitation energy = Rhc 1 1 2 - 1 2 2 = Rhc 3 4 ∴ 3 4 Rhc = V eV ∴ Rhc = 4 V 3 eV
