    His theory said that all matter consisted of snaller particles that couldn't be divided.He asked a question thats is if you break matter then how many times couldyou break it again untill you can't?

    He belived that there was no limit on the amount of times matter could be divided And all subbstances were made up of the 4 elements fire, air, water, and cold. His model described matter.
  • John Dalton

    Daltons theory said that all matter is made up of induvidual particles which are atoms that cannot be dividedd
  • J.J Thompson

    J.J Thompson
    Thompsons therory that atoms are made of even smaller particles.In his experiment he used an electric current and they helped prove his theory.

    He said that electrons move in orbit and that am atom had a central nucleus.
  • Ernest Rutherford

    Ernest Rutherford
  • Neils Bohr

    Neils Bohr
    He proved that electrons gain or lose energy when theymove between energy levals and that electrons move in circular orbit around the nucleus.
  • Ernest Marsden

    Ernest Marsden
    He did experiments that made a beaam pass throungh gold foil. His theory said that an atom has a dense positvly charged nucleus, and the electrons move randomly in the space around it.
  • Louis De Broglie

    Louis De Broglie
    He said electrons have propeties like waves
  • James Cadwick

    James Cadwick
    He said there were different partickes in an atoms nucleus and he found that there were protons and neutrons in the nucleus.
  • Erwin Schrodinger

    Erwin Schrodinger
    He did math equations to come up with the Electron Cloud Model.
