J. J. Thompson.
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.
The name was plum pudding.
its called the plum pudding model
Thomson's plum pudding model is the model of an atom in which an atom is regarded as a sphere of size 10^(-10)m radius and positively charged matter in which electrons were embedded. Thomson used the pudding as the positive charge and the plums as the negative charge. The plums are stuck in the pudding just as electrons are randomly found in an atom.
J.J. Thomson is credited with proposing the plum pudding model of the atom in 1904. This model suggested that the atom is composed of negatively charged electrons scattered throughout a positively charged "pudding" of matter.
The plum pudding model of the atom was put forward by J.J. Thomson.
J.J. Thomson, a British physicist, first proposed the plum pudding model of the atom in 1904. This model described the atom as a positively charged sphere with electrons embedded in it, similar to the seeds in a plum pudding.

JJ Thomson called his model of the atom the "plum pudding model." In this model, electrons were embedded in a positively charged sphere, resembling the distribution of plums within a British pudding dessert.

Atom
I think you're referring to JJ Thomson's model. It is more oftenly called the 'plum-pudding model'.
The scientist who proposed the idea of the atom as a hard sphere was J.J. Thomson. He later refined this model to include the concept of electrons embedded in a positively charged "plum pudding" to account for the behavior of atoms.
The Plum Pudding Model proposed by J.J. Thomson depicts electrons as dispersed throughout a positively charged atom, much like plums in a pudding. This model suggested that the atom is overall electrically neutral due to the balance of positive and negative charges. However, this model was later replaced by the Rutherford model which proposed a nucleus at the center of the atom surrounded by orbiting electrons.
