What partical did Thomson discover?
Thomson discovered the electron. By conducting experiments with cathode rays, he was able to determine the properties of these particles, which led to the discovery of the electron as a fundamental constituent of atoms.
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.
Who discovered the charge to mass ratio for the electrons?
Millikan found the charge of an electron by his famous oil drop experiment. J J Thomson determined the specific charge of the electron. That means the ratio of the charge of an electron to its mass. With these two values one can find the mass of electron by dividing the charge value by its specific charge.
What did J. J. Thomson experiment with?
J. J. Thomson experimented with cathode rays and discovered the electron, leading to the development of the plum pudding model of the atom.
What did the scientist Thomson discover?
J.J. Thomson discovered the electron in 1897. He conducted experiments with cathode rays that led him to propose the existence of these tiny, negatively charged particles. Thomson's discovery laid the foundation for our understanding of the structure of atoms.

J.j. Thomson
What year was electron found out about?
jj Thomson discovered the electron in the early 1900s
What was Joseph J. Thomson's contribution to chemistry?
J. J. Thomson discovered the electron and the isotopes.
Who discovered that atoms contain subatomic particles?
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.
What is the contribution of j j Thomson to the development of the periodic table?
JJ Thomson discovered the electron in 1897.
Did Antoine Lavoisier discover the electron?
The electron was discovered by J. J. Thomson and collaborators in 1897.
