  • Sir J.J. Thomson

    In 1897 Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.

  • Sir J.J. Thomson Observations

    Performed a series of experiments in 1897 designed to study the nature of electric discharge in a high-vacuum cathode-ray tube.Thomson discovered electrons and noticed that an atom can be divided. Also, he concluded atoms are made of positive cores and negatively charged particles within it.

  • Sir J.J Thomson Observation Explanation

    To test the properties of the particles,Thomson placed two opposite charged electric plates around the cathode ray. The cathode ray was deflected away from the negatively-charged electric plate and towards the positively-charged plate. This indicated that the cathode ray was composed of negatively-charged particles.

  • Sir J.J Thomson

    J.J. Thomson discovered the electron by experimenting cathode ray tube. He demonstrated that cathode rays were negatively charged.
