mar 28, 1897 - Discovery of Electrons: JJ Thompson discovered the electron by experimenting with applying high voltages to low-pressure gases. He used beams of particles that were attracted to positive charges. This meant that they had to be negatively charge. These were named electrons. The Dalton model that stated that atoms could not be split were revised, instead saying that negative particles were embedded in a cloud of positive charge.
