The electron is a fundamental subatomic particle that was identified and assigned the negative charge in 1897 by Sir John Joseph Thomson and his team of British physicists.
Charles Oatley in 1952 discovered the electron scanning microscope, but Max Knott created the first prototype of the SEM in 1935.
Thomson, Townsend and Wilson are credited for the discovery of electron in 1991.
J.J. Thomson discovered the first subatomic particle, the electron, in the late 19th century through his experiments with cathode rays. This discovery led to the understanding that atoms contain subatomic particles.
They were never invented. They were discovered by various people at various times: Ernest Rutherford effectively discovered protons, around 1910, with his famous gold film experiment. He is usually "officially" credited with the discovery for his work in 1919. The electron was discovered in 1897 by J.J. Thomson. The neutron was discovered in 1932 by James Chadwick.
Binomial particles like protons, neutrons, and electrons were discovered by multiple scientists. The electron was discovered by J.J. Thomson in 1897, the proton was discovered by Ernest Rutherford in 1919, and the neutron was discovered by James Chadwick in 1932.
Electron discovered by einstein probably that how fool
J.J.Thomson has discovered the electron in 1897
This particle was the electron in 1897 (J.J. Thomson).
The electron
i have no idea when it was discovered
the electron was first discovered in 1897 by Joseph john Thomson and the proton was discovered in 1913 by ernest Rutherford
The year of the electron discovery is considered 1896.
JJ Thomson
jj Thomson discovered the electron in the early 1900s
Voltaire
in 1897
Nuclear Stability was discovered in 1943 rght after the electron(1942)
