The modern periodic law states that the physical and chemical properties of the elements are periodic functions of their atomic numbers.

Modern periodic table is based on atomic number. Thus, the properties of elements are related to their atomic number or electronic configuration. Elements are arranged according to increasing order of atomic number. Elements with similar properties occur at regular intervals in the periodic table. The cause of periodicity in properties is due to recurrence of similar outer electronic configuration at certain regular intervals.
