The Atom Timeline

  • Dalton: Solid Sphere Model

    Dalton: Solid Sphere Model
    The first atomic model was developed and Dalton hypothesized that an atom is a solid sphere and can not be divided
  • Thompson: The Plum Pudding Model

    Thompson: The Plum Pudding Model
    Discovering that the electron was the negatively charge part in an atom.
  • Rutherford: The Nuclear Model

    Rutherford: The Nuclear Model
    shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths
  • Bohr: The Bohr Model

    Bohr: The Bohr Model
    made the model that depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus
  • Schrodinger: Quantum Mechanics Model

    Schrodinger: Quantum Mechanics Model
    used mathematical equations to describe the likelihood of finding an electron in a certain position.
