J.J. Thomson, a British physicist, is renowned for his discovery of the electron, the first subatomic particle. He revealed that cathode rays were made up of electrons, which have a small size and high charge-to-mass ratio. Thomson also identified the initial evidence of isotopes within a stable element and played a significant role in advancing mass spectrometry. His research on electricity conduction in gases led to him being awarded the Nobel Prize in Physics in 1906. Moreover, as an educator, Thomson guided numerous students who later received Nobel Prizes in various fields.
