    Dalton proposed that all matter is made of atoms and that these atoms cannot be broken into smaller particles.

    He raised into fame with his plum pudding model. He basically stated the atom was the smallest particle, but discovered as well that it had smaller ones called electrons. His drwaing showing this seems as a pudding.

    Rutherford shooted positively charged alpha particles through a gold foil. Most alpha particles passed throught, but sometimes, one bounced back. he deduced and discovered that: An gold atom is composed of the nucleous, and mainly empty space. What happened was that one time in a lot of times, the alpha particled crushed into the nucleous, and was deflected or bounced back. As well, he discovered that electrons move freely around the nucleous.
  • Bohr

    Bohr
    He suggested a more detailed structure of the atom by ussing the absorption and emmission spectra, which both of the use the light reflection on a prism, with the mixture of some hot/cold gas.
