The five main points of John Dalton's atomic theory are asfollowed: · Elements are made of tiny particles called atoms. · Allatoms of a given element are identical. · The atoms of a givenelement are different from those of any other element. · Atoms ofone element can combine with atoms of other elements to formcompounds. · A given compound always has the same relative numbersof types of atoms. · Atoms cannot be created, divided into smallerparticles, nor destroyed in the chemical process. A chemicalreaction simply changes the way atoms are grouped together.
