What Parts Of Daltons Atomic Theory No Longer Agree With The Current Picture Of An Atom?

There are two parts of Dalton’s atomic theory that are not the same as when Dalton conceived it. 1. Dalton said that all matter is composed of atoms. He assumed that atoms where indivisible. We now know about sub atomic particles and that atoms can be split. 2. Dalton stated that all atoms of a given element are alike. We now understand about ions and isotopes and that every atom of a given element is not always like the others.
