Don't Electrons in Bound States Radiate and Lose Energy?
I asked r/AskPhysics I hear that electrons in atoms are in bound states around the nucleus, smeared out rather than a point particle. If bound electron (let's say an excited state in hydrogen-like atom), has kinetic energy.. does it still 'move' in some way, and in the process, does it not radiate and energy? Or do things happen so that electron in a bound state will remain in the same energy state unless spontaneously excited/grounded to higher/lower states? I also hear that electrons prefer being in the lowest energy state allowed, and that the electron would be in 1s ground state, cuz it somehow has the lowest energy. The bound electron, whatever it is, is still negatively charged.. what is stopping thr thing from collapsing positive proton. Does that somehow have more energy than the ground state? I also hear, that when approaching absolute zero, something of electron losing more and more energy, and its some zero point energy due to uncertainty that somehow keeps elect...
