    Decmocritus(BC)
    He invinted the atom and said if you keep breaking down a substance you will get something that cant be broken down and found this by cutting a piece of bread.

  • Dalton

    Dalton
    He discorvered the atom is the small things that have different masses with different properties and he found this by using his imagination.

  • Thomson

    Thomson
    He found that there are electrons that are in postive matter and found this by using cathode rays to interact with electronic and magnetic fields and his experiment was called the pulmb pudding model.

  • Rutherford

    Rutherford
    He found that the nucleus was seperate with electrons around it and found this by using the gold foil project and said it looked like a circular nucleas with samll elctrons around it.

  • Bohr

    Bohr
    He found that the elctrons jump between energy levels and built of the gold foil experiment and thought the electrons orbit the nucleaus with outter rings like the solar system.

  • Heisenberg and Schrodinger

    Heisenberg and Schrodinger
    He found that the electrons float rather than them having a set travel path and found this by building off of Bhors model and he belived it looked like a circular nucleaus with protons and nuetrons in the middle with electrons on the outside.
