I am assuming your question is: "what are the sub atomic molecules inside and outside the nucleus of an atom?" Here is the answer: There are three subatomic particles, Protons Neutrons and Electrons. Protons are located inside the nucleus of an atom, along with Neutrons. Electrons are located outside the nucleus, inside things called energy levels, but i won't go into to much detail. Hope that answers your question
