Discovery of Electrons
Thomson's experiments revealed that cathode rays were composed of particles much lighter than hydrogen ions, leading to the conclusion that atoms could be split. He proposed the plum pudding model, where negatively charged electrons were distributed within a positively charged material, suggesting that the arrangement of these electrons determined the properties of different elements. This groundbreaking work laid the foundation for our understanding of atomic structure.In this clip
