He discovered this by firing Alpha particles at a gold foil and most alpha particles went through the foil and a few were deflected. The area where the alpha particles were deflected were assumed where the small dense positively charged nucleus was located. And electrons were scattered in the empty space out side the small nucleus.

Answer:
The plum-pudding model proposed that an atom is composed of negatively-charged particles floating within a sea of positive charges. This sea of positive charges served to counterbalance the negative charge on the electrons so that the atom remains neutral.
Explanation:
J.J. Thompson from experiments he conducted with the rays produced from a cathode tube to which a high voltage is applied across its two ends, discovered that these rays were negatively charged and had a mass much much smaller than the mass of any known atom. These negatively-charged rays were later called electrons. Since the atom was neutral in charge overall, J.J. Thompson then proposed the plum-pudding model.
The plum-pudding model proposed that an atom is composed of negatively-charged particles floating within a sea of positive charges. This sea of positive charges served to counterbalance the negative charge on the electrons so that the atom remains neutral. The name of this model was chosen because it resembled the English dessert, plum-pudding.
Answer:
sharing of electron
Explanation:
As seen in carbon. carbon has four electrons in his outermost shell and needs for electron by sharing of electrons it can gain it by another carbon
