What scientist is credited with the discovered of electron?
J.J. Thomson decided to find out for sure. Thomson was a physics professor at Cambridge University in the UK. He placed cathode tubes in electric and magnetic fields.
Who discovered electrons How did they discover it?
J.J. Thomson
In 1897, J.J. Thomson discovered the electron by experimenting with a Crookes, or cathode ray, tube. He demonstrated that cathode rays were negatively charged. In addition, he also studied positively charged particles in neon gas.
Is credited with the discovery of the electron?
Joseph John Thomson (J. J. Thomson, 1856-1940; see photo at American Institute of Physics) is widely recognized as the discoverer of the electron. Thomson was the Cavendish professor of Experimental Physics at Cambridge University and director of its Cavendish Laboratory from 1884 until 1919.

What was J.J. Thomson theory?
J.J. Thomson’s experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged “soup.”
What is J.J. Thomson known for?
Thomson, in full Sir Joseph John Thomson, (born December 18, 1856, Cheetham Hill, near Manchester, England—died August 30, 1940, Cambridge, Cambridgeshire), English physicist who helped revolutionize the knowledge of atomic structure by his discovery of the electron (1897).
What was JJ Thomson discovery?
On April 30, 1897, British physicist J.J. Thomson announced his discovery that atoms were made up of smaller components. Thomson, a highly-respected professor at Cambridge, determined the existence of electrons by studying cathode rays.
Who is electron father?
Sir J. J. Thomson
Sir Joseph John Thomson OM PRS (18 December 1856 – 30 August 1940) was a British physicist and Nobel Laureate in Physics, credited with the discovery of the electron, the first subatomic particle to be discovered….J. J. Thomson.

What do scientist associated with the discovery of the electron?
The value of this charge was first measured… The electron was discovered in 1897 by the English physicist J.J. Thomson during investigations of cathode rays. His discovery of electrons, which he initially called corpuscles, played a pivotal role in revolutionizing knowledge of atomic structure.
Who first discovered the existence of electrons?
The Discovery of the Electrons The electron was discovered in 1896, by the British physicist J. J. Thomson, using a cathode rays while doing discharge tube experiments. Thomson also determined e/m, ratio of the charge e to the mass m of the material particle which constituted these rays.
What instrument was used to discover the electron?
Thomson’s experiments with cathode ray tubes helped him to discover the electron. This ushered in a model of atomic structure referred to as the plum pudding model.
What scientist discovered the positively charged nucleus?
In 1911, Ernest Rutherford a scientist from New Zealand experimented to find the arrangement of electrons and positively charged particles i.e. protons in an atom. His experiment led to the discovery of a small, positively charged nucleus at the center of an atom.
