## Homework Statement

What are the energies of the ground state and the first two excited states of the He

^{+}ion?

## Homework Equations

E

_{n}= - E

_{o}/n

^{2}

## The Attempt at a Solution

n=1 for this problem (since there is only 1 electron) so the ground state would have the electron contained in the 1s subshell. Thus E= -13.6eV(1/1

^{2})=-13.6eV

The first excited state has the electron entering the 2s subshell, and the second excited state in the 2p subshell? What I'm getting confused about (assuming my solution for E for the ground state is correct) is that since n=1, the answer won't change depending on what subshell it is in according to how I am approaching the problem. And this I beleive is incorrect.... Any thoughts, help? Thanks!
