Storyboard Text

  • I, John Dalton, am an English chemist, physicist, and meteorologist. I propose the greatest discovery of all time.
  • My theory, the Dalton Atomic Theory, contains five key points1. 1. All matter consists of tiny particles called atoms2. Atoms are indestructible and unchangeable3. Elements are characterized by the weight of their atoms4. In chemical reactions, atoms combine in small, whole-number ratios5. When elements react, their atoms may combine in more than one whole number ratio
  • I discovered the electron, which is the negative charge of the atom. I proposed a model of an atom as a sphere of positive matter
  • Not so fast. I. J.J. Thomson, have to disprove your theory that atoms are indivisible. When elements are excited by an electrical current, atoms break down into two parts.
