  • Dalton: Solid Sphere Model

    Hypothesized that an atom is a solid sphere that could not be divided into smaller particles.
  • Thomson: The Plum Pudding Model

    Atom is composed of electrons surrounded by a soup of positive charges to balance the electrons negative charges
  • Rutherford: The Nuclear Model

    Shows that an atom is mostly empty space with electrons orbiting a positively charged nucleus in set paths
  • Bohr: The Bohr Model

    A system that consists of small dense nucleus surrounded by orbiting electrons.
  • Schrodinger: Quantum Mechanics Model

    The use of mathematical equations to describe the likelihood of finding an electron in a certain position
