I understand now how to find the energies of the first two excited states by using the ground state energy. I do not however understand how to get the ground state energy without looking it up. What formula would I use?

Ok I see where the textbook was getting the -13.6 eV from now, I was looking at the section on the Hydrogen atom since I knew I needed to be dealing with one electron atoms. According to the textbook it is -78.98 eV. So then is the energy in the two excited states goin to be this value squared?

Homework Statement What are the energies of the ground state and the first two excited states of the He+ ion? Homework Equations En= - Eo/n2 The Attempt at a Solution n=1 for this problem (since there is only 1 electron) so the ground state would have the electron...

I do now... Even though I read that response too late. The grader of my homework gave me full credit anyways for a sub-par result... But I appreciate the response because it let me on the right track after the fact!

I believe that would be 1s
