  • "Dalton's model explained that atoms were tiny invisibly, indestructible particles; And that each had a certain mass, size, and chemical behavior that determined by what kind of element they were."
  • Dalton thought that atoms looked like billiard balls from pool. 
  • J.J Thomson's atomic model was different because it was a sphere embedded with electrons. The sphere had positive charges throughout it.  
  • The negatively charged particles were also scattered across this model.

  • The atom is made of electrons that are surrounded by a group of positive charged electrons by a group of positive charges to balance the electrons negative charges. This is like negatively charged plums that are surrounded by positively charged pudding.

  • Thomson discovered the electron in 1897 and proposed the plum pudding model of the atom in 1904 before the discovery of the atomic nucleus.
  • He wanted to include the electron in the atomic model. In his model, the atom is composed of electrons (he called them "corpuscles")

Thomson made his new model more intricate and detailed.
