Homework Statement The question was, you have a Helium ion with one electron in its ground state. Then a second electron is added to the n = 10 level. What effect does the second electron have the first electron that is nearest the nucleus? Is the energy increased or decreased? Homework...

Hi, This is probably a really simple question, I am just trying to get my head around why electron-electron-interactions raise the energy level. If electrons repulse each other, why does this cause the energy levels to increase? Thanks
