    Rutherford proposed a central nucleus2 with protons and neutrons, with electrons orbiting around the nucleus.

    1. atom: The smallest possible unit of matter that still maintains an element’s identity during chemical reactions. Atoms contain one or more protons and neutrons (except hydrogen (H), which normally contains no neutrons) in a nucleus around which one or more electrons move.
