ATOM
... John Dalton (1766-1844) is the father of the chemical atomic theory. He proposed an "atomic theory" with spherical solid atoms based upon measurable properties of mass. The main principles of his theory: chemical elements are made of atoms; atoms of different elements have different masses; atoms of ...
