Modern Periodic Law
✌️✔️In the year 1913 A.D, An English scientist Henry Moseley demonstrated, with the help of experiments done using X-ray tube , that the atomic number ( Z ) of an element corresponds to the positive charge on the nucleus or the number of the protons in the nucleus of an atom.
✌️✔️This revealed that "Atomic number" is a more fundamental property of an element than it's atomic mass.
✌️✔️Thus, Accordingly, the statement of the modern periodic law was stated as follows :-
✌️✔️" Properties of elements are a periodic function of the atomic numbers. "
