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.

El modelo atómico de Thomson (modelo "del pudín o pastel de pasas") es un modelo de estructura atómica propuesto en 1904 por Thomson, quien también había descubierto el electrón en 1897, 1 pocos años antes del descubrimiento del protón y del neutrón.
16 de dic. de 2022 · El modelo atómico de Thomson, también conocido como el modelo del pudín con pasas, fue desarrollado por Joseph John Thomson (18 de Diciembre de 1856 - 27 de julio de 1940) en el año 1904. Sir Joseph John Thomson fue un científico británico que descubrió la primera partícula subatómica, el electrón.
27 de jul. de 2020 · Última edición el 27 de julio de 2020 . El modelo atómico de Thomson fue creado por el celebrado físico inglés J. J. Thomson, quien descubrió el electrón. Por este descubrimiento y sus trabajos acerca de la conducción eléctrica en los gases, fue galardonado en 1906 con el Premio Nobel de Física.
J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."

The plum pudding model is an obsolete scientific model of the atom. It was first proposed by J. J. Thomson in 1904 following his discovery of the electron in 1897 and subsequently rendered obsolete by Ernest Rutherford's discovery of the atomic nucleus in 1911.
