What did Dalton think?
John thought that atom were like hard tiny balls. Elements can't be broken down and that elements have its own different form in mass.
He also thought that the atoms of different elements could be identified by there differences in their weight. John then found out that all matter is composed of atoms, “atoms cannot be made or destroyed, all atoms of the same element are identical, different elements have different types of atoms, chemical reactions occur when atoms are rearranged and compounds are formed from atoms of the constituent elements |

What did J.J think?
J.J thought that an electron was a negatively charged particle that was much smaller then the atom. He then thought that the tiny particles must have come from inside the atom. The tiny negatively charged electrons must have a postive charge around it,
and that the electrons carry no overall charge, so the charges must balance out. |

What did Rutherford think?
Ernest changed the results and suggested a different model for the atom, he thought Thomsons model could be right, and thought that the positive charge would be planted in a tiny volume in the center of the atom otherwise the alpha particles fired at the foil would never be repeeled back towards the source. This model above is showing the electrons orbited around the center of the atom.
