3. all atoom of an element are identical and different from those of other element. thus hydrogen consist of only the atom of oxygen. the atom of hydrogen differ from the atom of oxygen.
4. atom of element combine in the ratio of whole numbers of compound -atoms of a new substance the compound atoms of a particular substance are identical in all properties , and differ from those of other substance.
