John Dalton (1766 – 1844): John Dalton was an English chemist. His ideas form the atomic theory of matter. Here are his ideas. All elements are composed (made up) of atoms. It is impossible to divide or destroy an atom. All atoms of the same elements are alike. (One atom of oxygen is like another atom of oxygen.) Atoms of different elements are different.

Oct 13, 2016  · It wasn’t until 1803 that the English chemist John Dalton started to develop a more scientific definition of the atom.
