Modern Law of the Elements
The modern periodic law states that, "the physical and chemical properties of elements are periodic functions of their atomic numbers."
It is important to remember that before our "modern" periodic law, the Periodic Table of Elements was organized according to increasing atomic weights, and not by atomic number.
English chemist John Newlands and Russian chemist, Dmitri Mendeleev ("father of the Periodic Table"), both categorized the elements on the basis of increasing atomic weights.
The present law (and method of organization) was applied first by Henry Moseley in 1914.
