The electron -- couple questions Couple questions on the electron: First, as an accelerating charged body, an electron radiates electromagnetic energy in the form of photons (wiki). But I learned that photons are only emmited when an electron transitions energy states. It would seem to still be accelerating in its orbital even when staying in the same energy state. So why not continue to radiate photons while remaining in the same energy state? Two, is the spin of an electron an inherent characterisitc of THAT particluar electron, or can the spin of any given electron switch from, say, up to down? In other words, is it a mechanical property of its motion, like a spinning ball, or is it a structural characteristic of the particle itself, like chirality in identical molecules?
