        Schrödinger
        
        Schrödinger showed that the quantization of the hydrogen atom's energy levels could be calculated from the Schrödinger equation
        
        Schrödinger equation, could describe how the wave function of a quantum mechanical system
        
        Bohr
        
        He proposed a theory for the hydrogen atom based on quantum theory
        
        Electrons should move around the nucleus but only in prescribed orbits
        
        When jumping from one orbit to another with lower energy, a light quantum is emitted
        
        Rutherford
        
        He found that the atom is mostly empty space
        
        all of its mass concentrated in a tiny central nucleus
        
        The nucleus is positively charged and surrounded at a great distance by the negatively charged electrons
      - Thomson
        
        atom consisting of positive and negative charges
        
        Atom has equal amounts of charges so that an atom would be electrically neutral
        
        He proposed the atom was a sphere
    - - atoms, indivisible and indestructible building blocks
      - all atoms of an element were identical, different elements had atoms of different size's and mass's
      - Dalton thought that chemical reactions resulted in the rearrangement of the atoms.
      - all compounds were composed of different amounts of these atoms in defined ratios
