### Energy Levels

Dr. Lavelle mentioned this briefly but if an electron is somehow excited to the second energy level and then is able to jump to the third energy level, when it emits energy does it go back to the second energy level then the first or just drops straight back to the first?

### Re: Energy Levels

It depends on the energy of the incoming photon

Yes, for example if the energy of the incoming photon matches the energy difference between n=3 and n=1 then the electron will move to n=1, but if the energy of the incoming photon matches the energy difference between n=3 and n=2 then the electron will only move to n=2.

### Re: Energy Levels

An electron cannot be between two energy levels; n is a discrete, whole number, thus the energy of the incoming photon has to be the exact energy difference if an electron is to change levels.
