Question

Find the energies in ev of the first three excited States of the hydrogen atom

Answer 1

For hydrogen-like atoms, i.e. H , He+ , Li2+ , etc., the energy levels are given by:

1. En=−Z2⋅13.61 eVn2. where Z is the atomic number and n is the quantum level.

2. E2=−22⋅13.61 eV22. =−13.61 eV.

3. E1=−22⋅13.61 eV12. =−54.44 eV.
