WebTeori Atom J. Thomson. Pada tahun 1897, J. Thomson melakukan eksperimen dengan sinar katoda. Eksperimen tersebut menunjukkan bahwa sinar katoda terdefleksi (terbelokkan) oleh medan magnet maupun medan listrik. Hal ini menunjukkan bahwa sinar katoda merupakan radiasi partikel yang bermuatan listrik. WebThomson first announced his idea that cathode rays were corpuscles at a Friday evening meeting of the Royal Institution in late April 1897. The suggestion put forth by Thomson that the corpuscles were about one thousand times smaller than the size of the then smallest particle known, the hydrogen atom, caused a stir in the scientific community.
