Gold foil experimentErnest Rutherford discovered the proton through his gold foil experiment1. He bombarded a thin sheet of gold with alpha particles and noticed that while most passed straight through, some were deflected at large angles. Rutherford proved that the nucleus of a hydrogen atom, which is just a proton, is present in the nuclei of all atoms23. He is also credited with developing the atomic numbering system alongside Henry Moseley4.Learn more:✕This summary was generated using AI based on multiple online sources.
