I've been studying chemistry (I know this is a physics page) and I've read that electrons are supposed to lose energy because they are moving in an electric field (I know this is not actually happening). My question would be why are they supposed to lose energy? It is because they are attracted toward the center of the atom by the positive charge of protons?
It's the coulomb force here acting as a centrifugal force, keeping the electrons in orbit? But at the same time losing energy because accelerating?
