Ok so. There is a confusing aspect of the electron, you can’t tell them apart from each other, every electron is exactly the same. There is a thought experiment/theory that is very unlikely but not 100% off the table. All electrons look alike because they are the same electron traveling forwards through time as an electron and backwards in time as a positron. So there is only one electron in the universe. It’s called the one electron theory and was thought up by John Wheeler.

It’s been a while since I took Modern physics, so take my yammerings with a grain of salt. You want to know more about the atomic model or relative physics?
