Ok, so I have been searching around the internet for an answer to this and have not found anything besides the fact that electrons move in a quantum way, that is jumping from one place to another without passing through the space between those two places, which I am aware of. So the two main aspects of this question that I am confused about are: 1. What causes electrons to jump from orbit to orbit without any human influence like heating it when it is going around a nucleus? and 2. After having read about the double slit experiment, I was confused about what the electron in the test was orbiting around if it was just an electron itself; how could it go about its normal movements without a nucleus as its center? Thank you in advance!
