Rutherford tracked the motion of tiny, positively charged particles shot through a thin sheet of gold foil. Some particles traveled in a straight line and some were deflected at different angles. Which statement best describes what Rutherford concluded from the motion of the particles?

please help Rutherford's famous gold foil experiments shot heavy particles at a thin sheet of gold foil. What did he observe, and why did these observations eventually result in the addition of a nucleus to the atomic model? Some of the heavy particles bounced off the foil, because there are positive particles spread throughout the atom. Some of the heavy particles bounced off the foil, because there is a dense, positive area in the atom. The heavy particles all passed straight through the foil, because the atoms are mostly empty space. The heavy particles all bounced off the foil, because the subatomic particles have mass and volume. |
