Thomson atomic model, earliest theoretical description of the inner structure of atoms, proposed about 1900 by William Thomson (Lord Kelvin) and strongly supported by Sir Joseph John Thomson, who had discovered (1897) the electron, a negatively charged part of every atom.

Sir Joseph John Thomson (18 December 1856 – 30 August 1940) was an English physicist who received the Nobel Prize in Physics in 1906 for his discovery of the electron, the first subatomic particle to be found.
18 Οκτ 2024 · J.J. Thomson, English physicist who helped revolutionize the knowledge of atomic structure by his discovery of the electron (1897). He received the Nobel Prize for Physics in 1906 and was knighted two years later. Learn more about his life, career, and legacy.
It was first proposed by J. J. Thomson in 1904 following his discovery of the electron in 1897, and was rendered obsolete by Ernest Rutherford 's discovery of the atomic nucleus in 1911. The model tried to account for two properties of atoms then known: that there are electrons, and that atoms have no net electric charge.
25 Φεβ 2020 · The J.J. Thomson contribution to science helped revolutionize the understanding of atomic structure. He contributed extensively to the field of physics and chemistry by discovering the existence of electrons, developing the mass spectrometer and determining the presence of isotopes.
The British physicist Joseph John “J. J.” Thomson (1856–1940) performed a series of experiments in 1897 designed to study the nature of electric discharge in a high-vacuum cathode-ray tube, an area being investigated by many scientists at the time.
3 Ιουλ 2024 · The Plum Pudding Model, proposed by J.J. Thomson in 1904, was his conceptual model of the atom, developed shortly after his discovery of the electron. In this model, Thomson envisioned the atom as a sphere of positive charge with negatively charged electrons embedded within it, much like raisins in a plum pudding (a popular British dessert).
