PLUM PUDDING MODEL/RAISIN BREAD MODEL Flashcards
In 1897, Sir ———— discovered the electrons through an experiment that made use of a cathode ray tube.
Joseph John Thomson
is one of the subatomic particles of an atom and it is negatively charge.
Electrons
He also proposed the plum pudding model.
Joseph John Thomson
He believed that the atom was a large, positive, solid sphere.
Joseph John Thomson
The negatively charged electrons were embedded in the positively charged sphere.
The positive charges around the sphere would spread out as much as possible while the electrons (plum) would be distributed around the positive atoms (pudding) evenly.
