How did j. j. thomson discover electrons
WebJ.J. Thomson decided to find out for sure. Thomson was a physics professor at Cambridge University in the UK. He placed cathode tubes in electric and magnetic fields. He knew that these... WebThomson determined that charged particles much lighter than atoms, particles that we now call electrons made up cathode rays. Cathode rays are formed when electrons emitted from one electrode and travel to another when a voltage is applied in a vacuum.
