Homework Statement
If the total energy needed to remove an electron from a hydrogen atom is 24.6 eV, what is the distance that the electron is from the nucleus?
Homework Equations
I'm not really sure...I know that the answer is r = 5.85\times10^-11.
The Attempt at a Solution
As you can see, I know the answer, but I'm just not sure how to get to it. So far, I have thought of applying this process:
E_{e} = \frac{kq_{1}q_{2}}{r}
Technically, I get the answer if I sub in:q_{1}=q_{2}=e, E_{e}=24.6e, and solve for r.
Is this the correct process? I'm not really sure about the rationale behind it...lol I'm almost positive that there is another way.
