Question

Quizplus · Accepted Answer

Rutherford's experiment with alpha particle scattering by gold foil established that the majority of atoms are empty space and that the positive charge and most of the mass of an atom is concentrated in a small, dense region called the nucleus. This shows that protons are not evenly distributed throughout an atom.
