THOMSON PLUM PUDDING MODEL EXPLAINS THAT EVERY ATOM IS MADE UP OF ELECTRON WHICH ARE NEGATIVELY CHARGED AND PROTONS WHICH ARE POSITIVELY CHARGED. LATER THERE WERE SCIENTIST WHICH STUDIED ATOMS MORE CLEARLY AND THEN FOUND THERE IS A NUCLEUS IN BETWEEN WHICH CONTAINS IF NEUTRONS WHICH HAVE EQUAL NO. OF CHARGE.

The 'plum pudding' model of the atom was proposed by JJ Thomson, who had also discovered the electron. It was put forth before the discovery of the nucleus. According to this model, the atom is a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge. The electrons are like plums in a pudding. However, this model was discarded when Rutherford performed the famous alpha particle scattering experiment and put forth his model of the atom, which was similar to our solar system, with electrons revolving around a positively charged, dense nucleus.
