WebMar 16, 2024 · J.J. 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). He received the Nobel Prize for Physics … WebThomsons Experiment mit Kathodenstrahlen erlaubte die Formulierung der folgenden wissenschaftlichen Postulate: - Der Kathodenstrahl besteht aus subatomaren Teilchen mit negativer Ladung. Thomson definierte diese Partikel zunächst als "Korpuskeln". - Die Masse jedes subatomaren Teilchens ist nur 0,0005 mal die Masse eines Wasserstoffatoms.

WebAug 25, 2024 · The charge of an electron is sometimes referred to as the elementary charge and usually denoted by e. The elementary charge is a fundamental physical constant and as of May 2024, its value is defined to be exactly 1.602176634 × 10 − 19 C. Since the charge of an electron was now known due to Millikan’s research, and the charge-to-mass ratio ... WebJ.J. Thomson discovered the electron in 1897 and led the Cavendish Laboratory into a world-class research institution. His work opened the field of subatomic physics to experimental investigation and helped unravel the inner workings of the atom. He developed the "plum pudding" model of the atom. fulton station houston
