AQA A Level Physics - energy levels
Hey guys, quick question, I'll keep it short:
I understand that electrons sit in 'energy levels' around the nucleus, and can move to a higher energy level when they're excited. Question is: does an electron have more or less energy when it's closer to the nucleus? Thanks !

Hi! I think it has more energy further from the nucleus because the distance increases so the potential increases, but in terms of AQA Physics, I don't think the distance from nucleus is that relevant, it's just the idea of electron energies increasing and releasing in discrete amounts. That's what I understand from Google anyway. Hope that helps!

Energy levels have negative energy values. The ground state (n = 1) in hydrogen is -13.6 eV. You need to know about the energy levels not distances.
