in the nucleus and the atomic weight?
Rutherford deduced this because the alpha particles did not bounce off the gold foil atoms and instead passed straight through is differences between the number of protons in the nucleus and the atomic weight.
A proton is one of the three primary particles that make up an atom. This is a tiny, dense region in the core of the atom. Protons have one (+1) positive electrical charge and weigh one atomic mass unit, or approximately 1.671027 kilograms.
Thus, Rutherford deduced this because the alpha particles
