The present periodic table is arranged in order of increasing atomic numbers not the atomic weights , before modern periodic law the elements were arranged on the basis of atomic weights.
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
