Well Mendeleev constructed the first well detailed periodic table based on the atomic masses of each element. The elements were arranged in an increasing order of their atomic masses. His principle was that the increasing Atomic Mass determines the periodic properties of each element. This eventually led him to predict new elements. But his table had some flaws one of them being that hydrogen had same characteristics as that of alkali metals and halogens. Another being that the isotopes had no place in the Periodic Table.
