How was Thomson's model of the atom refuted?
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 [1] following his discovery of the electron in 1897 and subsequently rendered obsolete by Ernest Rutherford 's discovery of the atomic nucleus in 1911.
Charles T. R. Wilson. John Zeleny. Sir Joseph John Thomson OM FRS [1] (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 found.
Jun 14, 2021 · The goal of each atomic model was to accurately represent all of the experimental evidence about atoms in the simplest way possible. Following the discovery of the electron, J.J. Thomson developed what became known as the " plum pudding " model in 1904.
Thomson conjectured that the electron was a fundamental building block of matter or atoms, and along with his colleagues at Cambridge attempted to build upon his discovery in order to model atomic structure with theoretical speculations and extensive experimental investigations, particularly scattering experiments.
May 30, 2021 · According to J.J. Thomson's atomic model, the atom consists of electrons placed in a positively charged "soup,” which compensates for the electrically negative charges of the electrons. According to this model, electrons could spin freely in a drop or cloud of such a positively charged substance.
