Design a test to determine whether thorium-234 also emits particles. First, explain how Rutherford’s experiment measured positive particles aimed at the gold foil. Then, explain a test that might detect whether particles are emitted from thorium-234. Last, explain why it would be more difficult to detect the release of neutrons than protons.
