I can't seem to find this answer anywhere online. I am trying to work through a solid state physics textbook for research and this popped into my head. I don't have any mathematical background on quantum mechanics and other more advanced physics topics.
Obviously, atoms can't be described using similar terms to a star system for the most part. Knowing that, I was wondering if having an atom with two or more orbiting nuclei would be a possibility. From my understanding, nuclei can really only be stable up to certain sizes which is why you get atomic decaying. Would there be a set of subatomic forces that might allow for this sort of equilibrium to occur?
