Storyboard Text

  • I am Democritus. I have proposed that matter is composed of small particles called "atomos".
  • "atomos" are indivisible, and are a plain solid ball
  • So in a solid object, it looks like this.
  • I'm JJ Thomson. I proposed that atoms have sub-atomic particles, like electrons.
  • In my atomic model, atoms are mostly positively charged, like a dough in a bun. The negatively charged ones called electrons are found inside the dough.
