Dmitri arranged elements in order of increasing atomic masses. He considered chemical properties of the elements.
Henry Gwyn Jeffreys Moseley was an English physicist. He developed the Law in X-ray Spectra that helped sort the chemical elements of the periodic table of the elements in a logical order.
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
