उत्तर
It states that "The physical and chemical properties of the elements are a periodic function of their atomic numbers." According to this law, if we arrange the elements based on their increasing atomic numbers, we find that the elements with similar physical and chemical behaviour will be grouped together after a certain interval of elements.
