Gold foil experimentErnest Rutherford discovered the proton through his gold foil experiment. By bombarding a thin sheet of gold with alpha particles, he observed that some were deflected at large angles, leading him to conclude that these hydrogen nuclei were fundamental components of all atomic nuclei and named them protons1234.Learn more:✕This summary was generated using AI based on multiple online sources.
