In the late 19 th century, physicist J.J. Thomson began experimenting with cathode ray tubes.Cathode ray tubes are sealed glass tubes from which most of the air has been evacuated. A high voltage is applied across two electrodes at one end of the tube, which causes a beam of particles to flow from the cathode (the negatively-charged electrode) to the anode (the positively-charged electrode).

J.J. Thomson abandonó su hipótesis del "átomo nebular" de 1890, que se basaba en la teoría del vórtice del átomo, en la que los átomos estaban compuestos por vórtices inmateriales, y sugirió que había similitudes entre la disposición de los vórtices y la regularidad periódica encontrada entre los elementos químicos.
