## Homework Statement

How much energy is required to remove an electron from a hydrogen atom in a state with n = 8?

## Homework Equations

E = - (1 / 4pi*epsilon_0)(me^4/2(h-bar)^2)(1/n^2)

Where E is the total energy of the electron.

## The Attempt at a Solution

I know that if you solve the above equation for the ground state (n = 1), the binding energy of the electron is equal to E, but I'm not so sure about excited states. Do I merely solve the above equation for n = 8, or is there something I'm missing?
