Who discovered electron ?
What Michael Faraday found in his experiment ?
Who did the first experiment to find (e-)?
I think when we open 11-science , then open structure of atom , then its concept ,, there is wrongly written that ,, {discovery of atom (Michael Faraday's cathode ray tube experiment)} , please check it if it's wrong , and please ans these three question in one forum !!

Dear student,

1) The electron was identified and assigned the negative charge in 1897 by J.J. Thomson and his team of British physicists. They performed experiments indicating that cathode rays really were unique particles, rather than waves, atoms, or molecules as was believed earlier.

​​​​​​The brief explanation for the discovery of electron is described as:

Discovery of Electron (Michael Faraday’s Cathode Ray Discharge Tube Experiment)

  • Experimental Setup:

    The glass tube is partially evacuated (Low pressure inside the tube)

    ​​​​​Very high voltage is applied across the electrodes
  • Observation:
    Stream of particles move from the cathode (− ve) to the anode (+ ve) −−− known as cathode rays or cathode ray particles

  • Results :

    • Cathode rays move from the cathode to the anode.

    • Cathode rays are not visible. They can be observed with the help of phosphorescent or fluorescent materials (such as zinc sulphide).

    • These rays travel in a straight line in the absence of electric and magnetic fields.

    • The behaviour of cathode rays is similar to negatively charged particles (electrons) in the presence of an electrical or a magnetic field.

    • Characteristics of cathode rays do not depend upon: the material of the electrodes and the nature of the gas present in the tube

  • Conclusions:
    -Cathode rays consist of electrons
    - Electrons are the basic units of all atoms.
