Question

match each experiment to the subatomic particle it helped discover. subatomic particle experiment electron cathode ray tube experiment proton beryllium sheet experiment neutron gold foil experiment

Explanation:

• Electron: Discovered via the cathode ray tube experiment (J.J. Thomson showed cathode rays are electrons).
• Proton: The gold foil experiment (Rutherford’s work led to understanding atomic structure, including protons in the nucleus).
• Neutron: Discovered in the beryllium sheet experiment (Chadwick’s experiment with beryllium and radiation identified neutrons).

Answer:

Electron - Cathode ray tube experiment
Proton - Gold foil experiment
Neutron - Beryllium sheet experiment
