    Solution:

    According to the contemporary periodic law, an element's chemical and physical characteristics are a periodic function of its atomic number and electronic configuration. After some predetermined regular intervals, the items with related properties repeat. If the elements are arranged in ascending order of their rising atomic numbers, this recurrence will take place.
