How was the electron discovered?

To understand the discovery of the electron, it's essential to grasp the basics of cathode rays. In the late 19th century, scientists observed that when an electric current was passed through a vacuum tube, a beam of light was emitted from the cathode (negatively charged electrode). JJ Thomson, a British physicist, conducted experiments using cathode rays and discovered that the beam was composed of tiny, negatively charged particles. These particles, now known as electrons, were found to be incredibly small, with a charge 1/1836 that of a hydrogen ion.

The electron is one of the three primary subatomic particles, along with protons and neutrons, that make up an atom. Electrons orbit the nucleus, and their arrangement determines the chemical properties of an element.
