Rutherford discovered the proton during his gold foil experiment in which he shot a beam of radioactive particles at a piece of gold foil. During his experiment, pictured to the left, protons repelled the beam back. What kind of beam did Rutherford use? Justify your claim with evidence and reasoning.
