How to calculate ionization energy for the Nth level?
« on: May 28, 2010, 03:25:49 AM »
I had this question on a test today but had no idea how to solve it. It didn't help that my teacher only talked about ionization energy for about 2 minutes in class last week. Here is the question:

The energy of an election is (-1312 KJ/mol) / n squared

What is the ionization energy of an electron from the n=3 level?

When n is 3, what is the energy? When n is, say, 1000, what is the energy?

I don't think it's as simple as subbing 3 in for n in the equation. At least I hope it's not that easy

It is that simply. The whole idea behind energy levels is the fact that energy is quantized.
