Who discover the 3 subatomic particle?
Neutron James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutheford, 1919
When did JJ Thomson discover the electron?
J.J. Thomson discovered the electron in 1897 while conducting experiments on cathode rays. He observed that these rays could be deflected by electric and magnetic fields, leading him to propose the existence of a negatively charged particle within the atom, which he named the electron.
What is the subatomic particle that was discovered in 1932?
Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
What is J J Thomson known for?
J. J. Thomson is known for discovering the electron and formulating the plum pudding model of the atom. He was awarded the Nobel Prize in Physics in 1906 for his work on the conduction of electricity in gases.
