PLEASE HELP!! Uranium is the element used in nuclear power plants. It naturally emits particles from its nucleus. This releases energy that heats water to produce steam. The steam turns a turbine that produces electricity. The table below shows uranium-238 and thorium-234, the isotope that forms when the nucleus of uranium-238 emits a particle.

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.
