Excited electrons' behaviour, how do they work?

Click For Summary
SUMMARY

This discussion centers on the behavior of excited electrons and their transition back to the ground state, primarily through photon emission. It highlights the photoelectric effect, where excited electrons can indeed produce other electrons when interacting with photons. The conversation also touches on the concepts of electromagnetic (EM) waves, the absorption of light by electrons, and the relationship between light reflection and heat generation. The complexity of these interactions suggests a need for focused inquiries to enhance understanding.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with the photoelectric effect
  • Knowledge of electromagnetic wave behavior
  • Basic concepts of energy levels in atoms
NEXT STEPS
  • Research the photoelectric effect in detail, including its mathematical formulation

TL;DR
In how many ways can electrons go back to ground state?
Mainly I want to know the following thing: electrons when excited they tend to want to go back to ground state, right? One way is by photons, but how does that work? Accelerating charges creates EM waves, but in this case there was no acceleration, right? Or is the term accelerating only a way to say from high to normal (as we say that they "move a level of energy" when they don't physically move, they just have more energy than normal).

Another thing that I've read is the photoelectric phenomenon (is that how is called?), can excited electrons produce other electrons? As they produce photons, right? I think I read that they can, but then how can you get to choose wether if they are going to create a photon or a electron? For example: a metal receives all the lights and "makes sure" to create a electric field opposite (to neutralize) the EM wave's electric field, ending with the light (so no light that's going to go through the metal, right?). But also, electrons absorb light, do they? Or they just want to overcome the electric field, or both at the same time?
The magnetic field will keep moving? Or it will be absorbed by the metal too?

Another different but similar question: objects reflect light that is of the same color, right? Then it means that electrons gets to "choose" wether if to throw the photon or create heat? But... Isn't heat a infrared photon? And how do they "choose" if that wavelength or frequency is the wanted as photon or not?

Hopefully I didn't miss understood everything so badly.

Thank you for reading, I will appreciate concrete answers.

Sorry if there are mistakes, I'm a non English phone writing curious person right now xD

This is way too many questions covering way too much ground for a single PF discussion thread.

Please take some time to pick a single, specific scenario involving electrons, and formulate a single, specific question about something to do with that scenario that you find confusing or hard to understand. Then you can start a new thread to ask that question. That will lead to a much more focused and productive discussion.
