My question is simple and it is probably a very basic thing, but for some reason I don't know the answer to this question. Why does the electron orbit the nucleus and what is the importance of the electron orbiting the nucleus?? Why can't it just be the nucleus that makes up the atom? Whats so important about the electron?? (besides its practical uses, like how humans use it) Why is the electron apart of the atom?? So it would be of immense gratitude if someone could answers these questions. Thank you.
