Joseph John Thomson (J.J. Thomson) is widely credited with the discovery of the electron.
J.J. Thomson, a prominent figure in physics, held the esteemed position of Cavendish Professor of Experimental Physics at Cambridge University and served as the director of its Cavendish Laboratory from 1884 to 1919. His groundbreaking experiments and research led him to the identification of the electron as a subatomic particle. His work revolutionized our understanding of the atom.
His work is widely regarded as a major turning point in the field of physics, ushering in a new era of atomic research and particle physics. Thomson's discovery of the electron helped shape the development of modern electronics and solid-state physics.
| Discoverer | Key Role | Institution | Years of Service |
|---|---|---|---|
| J.J. Thomson | Discovered the electron | Cambridge University, Cavendish Laboratory | 1884-1919 |
Here are some insights into Thomson's discovery:
- Thomson used cathode ray tubes to conduct his experiments.
- He demonstrated that cathode rays were made of negatively charged particles, which he eventually named electrons.
- His discovery led to the understanding that atoms are not indivisible but rather are composed of smaller subatomic particles.
Thomson's contribution fundamentally changed the course of physics and chemistry, paving the way for countless scientific advancements and technological innovations.
