  2. Dalton thought atoms to be indivisible. JJ Thomson discovered electrons as a part of atoms and used the plum pudding model for the pieces of an atom.
    Rutherford was responsible for showing that the mass of an atom was concentrated in a very small center and the rest of the atoms was mostly space.
    Chadwick discovered the neutron, another "piece" of an atom.

  4. Do you not get the disconnection between "indivisible" by Dalton and "pieces" by the neutron and electrons. Read about the plum pudding by Thomson. Do you understand what Rutherford showed with his alpha particle bombardment experiment?
