Explanation:
Electron (e⁻) is the negatively charged subatomic particle that has an electric charge of -1e (−1.6022 ×10⁻¹⁹ C). It was discovered by the English physicist, Sir Joseph John Thomson (J. J. Thomson) in the year 1897 by the <em>cathode ray experiment</em>.
In the cathode ray experiment, <u>Sir Joseph John Thomson used the </u><em><u>cathode ray tubes</u></em><u> </u><u>to conclude the presence of negatively charged small subatomic particle, known as electrons, in all atoms.</u>
