The five main points of John Dalton's atomic theory are as followed: · Elements are made of tiny particles called atoms. · All atoms of a given element are identical. · The atoms of a given element are different from those of any other element. · Atoms of one element can combine with atoms of other elements to form compounds. · A given compound always has the same relative numbers of types of atoms. · Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process. A chemical reaction simply changes the way atoms are grouped together.The year was 1803.He also discovered the Dalton effect in ophtalmology, a gas law, prepared a list of atomic weights of chemical elements etc.
