The plum pudding model of the atom was put forward by J.J. Thomson.
Thomson's Plum Pudding Model was introduced in 1904.
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.
Thompson discovered the electron and proposed his "Plum Pudding" model of the atom, while Rutherford refined it, moving the electrons to shells outside the nucleus. Google "Rutherford Model" and "Plum Pudding Model" for more info
The nickname for Thompson's atomic model is the "plum pudding model." This model suggests that atoms are made up of a positively charged "pudding" with negatively charged electrons embedded within it, resembling plums in a pudding.
Thompson's plum pudding model was that the raisin were negatively charged (electrons) and that the rest of the pudding positively charged.
The name was plum pudding.
J.J. Thompson discovered the electron. His atomic model is also 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.
The plum pudding model was first introduced by J.J. Thomson in 1904 in the March edition of the UK's Philosophical Magazine. It was invalidated 5 years after during what is now known as the Rutherford gold foil experiment, an experiment designed to probe the atom.
