3. Atoms of a given element are identical in mass as well as in chemical properties.
4. Atoms of different elements have different masses and chemical properties.
5. Atoms combine in the ratio of small whole numbers to form compounds.
6. The relative numbers and kinds of atoms are constant in a given compound.
