I have a quick question about Photons

  1. May 28, 2015 #1
    When an electron passes from one atom to another is a photon emitted?

    I don't know what you mean by passes to another atom. When an electron make a transition from a higher energy level to a lower energy level, within the atom, then it emits a photon. This photon an energy which is equal to the different of energies between the 2 levels.

    rolotomassi, electrons are exchanged between atoms during chemical processes.

    No, as a general rule, photons are not necessary part of an atom-to-atom transport of an electron. The energies involved can be all just be heat energy.

    This energy is manifest as phonons and photons.

    Phonons aren't photons. The OP question is whether every atom-to-atom transfer involves an emitted photon. It doesn't.

    Phonons are an emergent phenomena, kind of like a wave in a bathtub. Since an electron is being emitted, I think it would suffice to say that a photon had just been absorbed by an atom, not emitted.

    How about that, hu? Yet you were referencing both.

    This thread will remain closed. Hawki, if you can frame a more specific question that clearly states what physical scenario you are interested in ("electron passes from one atom to another" is too vague and general), please feel free to start a new thread.
