The correct answer is
Thomson
Electron Discovery by J.J. Thomson
The electron was discovered by J.J. Thomson in the year 1897.
Thomson conducted experiments using cathode ray tubes. He demonstrated that cathode rays consisted of negatively charged particles, which he initially called "corpuscles". These particles were later named electrons. His work fundamentally changed the understanding of atomic structure.
Contributions of Other Scientists
- Ernest Rutherford: Known for discovering the atomic nucleus and the proton through his gold foil experiment.
- James Chadwick: Discovered the neutron in 1932.
- Niels Bohr: Proposed the Bohr model of the atom, explaining electron orbits and energy levels.
Therefore, J.J. Thomson is credited with the discovery of the electron.
The correct option is C.
