Answer

Electron was discovered by J.J. Thomson

J.J. Thomson, a British physicist, is credited with the discovery of the electron in 1897.

Thomson conducted a series of experiments using cathode rays, which are streams of negatively charged particles.

Through his experiments, Thomson was able to determine that cathode rays were composed of particles that were much smaller and lighter than atoms.

He proposed that these particles were negatively charged and named them electrons.

Thomson's discovery of the electron revolutionized the understanding of atomic structure and laid the foundation for the development of modern atomic theory.
