The gold foil experiment, because it proved that there were nuclei in the atoms
The name was plum pudding.
its called the plum pudding model
according to jj thomsons model of an atom,an atom consists of a positively charged sphere with electrons in it.however,it was later found that positively charged particles reside at the center of the atom called nucleus,and the electrons revolve around the nucleus.
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.
In the plum pudding model, electrons are mixed throughout a positively charged "pudding" of uniform density. The model was proposed by J.J. Thomson to describe the structure of the atom before the discovery of the nucleus.

Ernest Rutherford disproved the plum pudding model by conducting the gold foil experiment, where he observed that some alpha particles were deflected at large angles, indicating the presence of a small, dense nucleus within the atom, rather than a uniform positive charge distribution as proposed by the plum pudding model.

plum pudding
The plum pudding model of the atom was put forward by J.J. Thomson.
Rutherford's gold foil experiment disproved the plum pudding model by showing that atoms have a small, dense nucleus at their center, rather than being uniformly filled with positive charge. The experiment revealed that most of the alpha particles passed straight through the foil, indicating that atoms are mostly empty space with a concentrated positive charge at the center. This contradicted the plum pudding model, which proposed that positive charge was evenly distributed throughout the atom.
JJ Thomson's 1904 model was called the "plum pudding model." This model described the atom as a sphere of positive charge with electrons embedded throughout, like plums in a pudding. It was later replaced by the more accurate Rutherford model.
The ''plum pudding atomic model" is from J. J. Thomson, year 1904.
