How Does Proximity to Other Atoms Affect Electron Orbit Transitions?

Click For Summary

Discussion Overview

The discussion revolves around how the proximity of other charged atoms affects the energy required for electron orbit transitions. Participants explore the implications of electromagnetic fields on energy levels and the quantization of energy in this context.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions why the energy required for an electron to change orbit remains constant near other charged atoms.
  • Another participant asserts that the energy required does change in the presence of an electromagnetic field, suggesting that this is a complex topic requiring approximations for weak fields.
  • A different participant explains that without external fields, multiple states can have the same energy (degeneracy), but the introduction of an external field causes these energies to split, affecting the energy difference required for transitions.
  • One participant raises a concern about the implications of changing energy levels, questioning whether this means certain positions would prevent electron transitions due to quantization.
  • Another participant clarifies that the energy quantum changes based on circumstances, indicating that measuring transition energies can provide insights into atomic interactions.

Areas of Agreement / Disagreement

Participants express differing views on whether the energy required for electron transitions remains constant or changes in the presence of other charged atoms. The discussion includes both agreement on the complexity of the topic and disagreement on specific interpretations of energy changes.

Contextual Notes

Participants mention the need for approximations in calculations involving weak electromagnetic fields and the importance of understanding degeneracy and symmetry in quantum states. There is an acknowledgment of the complexities involved in determining energy differences and transitions.

as far as i know it takes certain amount of energy for an electron to change orbit now what i am wondering is why the energy required for an electron to change orbit doesn't change when close to let's say another positively(or)negatively charged atom

thank you for your time and sorry for the english

Hello,

The short answer is that, actually, the energy required to "change orbit" changes in the presence of an electromagnetic field.

To know exactly what changes is not so easy. We can perform easy calculation if the electromagnetic field is weak, but still we need some approximations.

If you are interested, try to read something amount Zeeman and Stark effects.

It changes.

Without external electric or magnetic fields, for most energy levels, there are several "orbits" (wave functions or simply states is a better word) that have the same energy (they are called "degenerate"). You can combine these in any way you want without changing the energy of the new state. Now if you add an external field, magnetic or electric or both, the energies of these states do become different (they split). You then have to find the "right" combination of states that solves the Schroedinger equation (or whatever model you use), i.e. find Eigenstates of the Hamiltonian that have a defined energy. Symmetry is an important help for doing that.

Now if the energies of the states change, then the energy difference between two states changes, too. This energy difference is probably what you refer to as "energy required for an electron to change orbit".
 
if the energy required does change and energy is quantized doesn't that mean that in some posistions the electron can't jump to a new orbit or am i understanding this incorrectly?
 
It just means that the energy quantum changes according to the circumstances.

This is very useful: You can measure the transition energies and thus find out about the interactions.
