Admin Who discovered electron and which experiment?
Summary. 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.”

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).
Who discovered electron and neutron?
02 Discovery of Electron, Proton and Neutron. Electrons were discovered by J.J. Thomson in 1897.
Who discovered the electron and how?
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 postulated the existence of the electron?

What is the name of the scientist who discovered the electron?
Weegy: J.J. Thompson is the name of the scientist who discovered the electron. User: What is the name of the scientist who discovered that atoms have positive charges? Weegy: Eugen Goldstein discovered in 1886 that atoms also have positive charges.
Who discovered that electron paths cannot be predicted?
Quick Answer. Werner Heisenberg is one of two scientists who said that electron paths cannot be predicted. A particle’s position (x) and momentum (p) cannot be measured with absolute precision, according to his uncertainty principle. The more accurately one of these values is known, the less accurately the other can be calculated.
