30 APR 2024 · On April 30, 1897, Joseph John (J.J.) Thomson, an English physicist, announced his discovery of the electron through a series of experiments conducted at the Cavendish Laboratory in Cambridge, England. This groundbreaking discovery marked a significant milestone in the field of atomic physics and revolutionized our understanding of the fundamental structure of matter. Thomson's experiments involved studying the properties of cathode rays, which are streams of negatively charged particles that are emitted from a cathode (negative electrode) in a vacuum tube. By applying electric and magnetic fields to these cathode rays, Thomson observed that they were deflected in a way that was consistent with the behavior of negatively charged particles. Through careful measurements and calculations, Thomson determined the charge-to-mass ratio of these particles, which he found to be much smaller than that of the lightest known atom at the time, hydrogen. This led him to conclude that these particles were subatomic, meaning they were smaller than atoms themselves. He named these particles "corpuscles," which later became known as electrons. Thomson's discovery of the electron challenged the prevailing belief that atoms were the smallest, indivisible units of matter. It opened up a whole new realm of subatomic physics and paved the way for further discoveries, such as the proton and neutron, which helped develop our modern understanding of atomic structure. For his groundbreaking work, J.J. Thomson was awarded the Nobel Prize in Physics in 1906. His discovery of the electron not only had profound implications for the field of physics but also laid the foundation for the development of numerous technological innovations, including electronic devices, computer chips, and modern telecommunications. So, on this day in science history, we celebrate the remarkable discovery of the electron by J.J.
