Atomic Electron Orbital Changes in High Voltage Capacitor Experiment

Click For Summary

Discussion Overview

The discussion revolves around the effects of a high voltage electric field on atomic electron orbitals, particularly whether electrons can change to higher orbitals when an atom is placed between two parallel capacitor plates. The inquiry includes considerations of energy sources for such transitions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions if electrons in an atom will change orbitals in a high voltage capacitor and seeks to understand the source of energy for such transitions.
  • Another participant suggests that the presence of an external electric field can alter the energy levels of the atom, indicating that the concept of maintaining old energy levels while transitioning to a higher state may not be accurate.
  • A different perspective is introduced by referencing a phenomenon involving a beam of electrons and a grating, suggesting that similar principles may apply, though the source of energy in that context remains debated.

Areas of Agreement / Disagreement

Participants express differing views on the impact of an external electric field on atomic orbitals, with no consensus on whether electrons will change orbitals or the mechanisms involved.

Contextual Notes

The discussion highlights the complexity of atomic behavior in electric fields, with considerations of electric polarizability and the generality of the question affecting the clarity of responses.

If an atom is passed between two parallel plates of a capacitor at a high voltage, will any of the electrons in the atom change orbital to go to a higher one?
If yes, then from where will the energy come for this?
 
Physics news on Phys.org
please, anybody?
 
The answer is not very easy because of the generality of your question.

I'll try to give you my point: In the presence of an external field some (if not all) orbitals will change. In other words, the energy levels of the atom can be different. So the picture of the atom in electric field keeping the old energy levels but jumping on a higher state is a little unrealistic. For sure, the electric polarisability of the atom is a very important parameter here.
 
This is sort of similar. It doesn't take atoms or a capacitor. Just a beam of electrons passing over a grating. It's called:

You can "google" to find out quite a few other links about it.

It's been a long-long time since it was discovered, and they're still fighting over the source of the energy.
