        The quantum mechanical model of the atom. It predict the odds of the location of the electron. Portrayted as a nucleus surrounded by an electron cluod were the most dense equals more odds of finding the electrons and less dense equals less odds.

        Explained why atoms emited light in fixed wavelenghts- named planetary model. Energy is transferred only in certain well defined quantities. When atoms jump from lower to higher orbits and it's absorbed when atoms jump from lower to higher orbits.
        
        Experimented with alfa particles. Explained that atoms consisted of a small, dense, positevely charged nucleus center with negatively charged electrons surrounding them.
        
        Explained some of the electrical properties of the atoms but failed to recognize the positive charges in the atom as particles. Atomic model as a plum puding.
        
        Formulated the first solid description of the atom concept. Composed the law of multiple proportion: chemical reaction resulted in the rearrangement of the reacting atom.
      - The solid state model, stated that the atom differ in size, shape, mass and that they are specific to the material that they are made up. Also, their composition and arrangement have an existing void.
