Why do electrons arrange into different “shells” around protons?

629 views

Like why are there two shells sometimes and three shells other times? Why are there different numbers of electrons on one shell than others? And what’s in between the protons and electrons?

I’m a little stoney and just can’t comprehend how something at this small of a scale has these “laws of nature.” Idk… hard to explain why this is fascinating me but it is. Especially the space in between the protons and electrons. Like are we all just empty space floating around?

They essentially want to find the constellation in which all forces acting upon them are equalized. Additionally electrons can only exist in a limited number of energy levels, which rises with the radius to the core. So electrons will always try to get near the core, but can only exist at very specific steps, and not at every possible distance. Think of this like groves in a wooden board around the middle. The electrons can only sit in these groves, and there can only be a limited number of electrons per grove.
