Sir J.J. ( Joseph John) Thomson
"The Father of Electrons"
Sir J.J. (Joseph John) Thomson [10/18/1856-8/30/1940], The Father of Electrons, was a British Physicist who discovered the existence of the Electron in 1897 (though the specific date is unknown) and won a Nobel Prize in Physics for his accomplishments. He studied at Cambridge University in Cambridge, England and discovered Electrons their. He first published the work based off the research off of a fellow scholar, James Clerk Maxwell [6/13/1831-11/5/1879], a Scottish Physicist who he never met.
The Plum Pudding Model
It was a NEW model of the atom called... "PLUM PUDDING" *model*! With the discovery of the Electron it changed the structure of the atom, it was a developed and made by this discovery and change from the Electron. With this "Plum Pudding" the atom was now thought to consist of positively charged spheres (later named Protons) or contained randomly scattered individual Electrons.
Early Mass Spectrometer
Not ONLY did he make "Plum Pudding", but he also made the Early Mass Spectrometer! He was awarded his Nobel Prize for this and his other research on electrical discharge gases. That's pretty much it.
- With his discovery of Electrons it made more scientist focus on the atomic structure.
- He and other scientist he worked with had trouble creating an atomic structure that explained the relationship between number of Electrons, Atomic Weight, Mechanical Stability, and Chemical Properties of Atoms.
- Thomson (again) won a Nobel Prize in 1906 for his Discovery and Study of Electrons which reshaped the way scientist think about the Periodic Table.
- Investigations of Electrons helped bring about the rapid invention and development of RADIO because of research in the electromagnetic "ether" of the Atmosphere.
- The discovery of Electrons help shape the atomic structure because it was later developed by Thomson. He stated that there is an electronic field surrounding the atom.
- Thomson taught Ernest Rutherford more about the Atomic Structure, HOWEVER Rutherford discovered more than Thomson.
Here are some EXTRA facts on J.J.T.
- In 1908 he was knighted for his accomplishments in science (Physics)
- His innovative "Plum Pudding" was quite unsuccessful for how sciencey it seemed at the time
- 7 of assistants also won NOBEL PRIZES for Physics.
- At the age of 21 he became a Cavendish Research Professor of Experimental Physics at Trinity College, Cambridge.
