Negative Energy Near the Nucleus

Postby An Dang 3F » Sat Oct 21, 2017 4:57 pm

Why is the energy most negative when it is near the nucleus? I understand that the equation E= -hR/n^2 shows that the energy will be a greater negative when n is a small number, but why is the energy negative?

I think it might be because electrons closer to the nucleus are in lower energy orbitals, so they have less potential energy. These electrons are also more stable than valence electrons (less likely to be shared/lost to another atom) which might also explain why they have lower energy.

Taking in mind that at n= infinity the potential energy of the electron is zero, the potential energy of the electron might be more negative as we approach the nucleus because the electron requires more energy to be released.
