WebErnest Rutherford discovered the nucleus and protons inside an atom. He showed that atoms have positively charged particles in their center that mostly consist of empty space. He called the positively charged particles protons, and the center of the atom the nucleus. Web10 de out. de 2024 · How were protons discovered? In 1909, Rutherford discovered proton in his famous gold foil experiment. In his gold foil experiment, Rutherford bombarded a beam of alpha particles on an ultrathin gold foil and then detected the scattered alpha particles in zinc sulfide (ZnS) screen. Most of the particles pass through the foil without …
