Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change then play a game to test your ideas. The electronic cloud determines the size, or volume, of the atom, but does not significantly contribute to mass electrons: mass = 0005 amu, charge = -1 electrons are found outside the nucleus they occupy orbitals atomic structure fundamentals.
