Explaining Rydberg Equation

Postby NatBrown1I » Mon Oct 22, 2018 9:09 am

Why is there a - sign in front of the equation E= -hR/n^2?

I think it's a convention, because when an electron's energy is zero, it's on the verge of escaping from the atom. If the electron is closer to the negative, it has less potential energy, so it becomes negative. The negative sign lets us differentiate between attached electrons and free electrons; the more negative the energy, the more tightly bound the electron is to the nucleus, and the higher the energy, the less stable the electron is.
