Henry showed that is more fundamental property than it’s .
Therefore Mendeleeve’s law was modified as: The physical and chemical properties of an element are the functions of their atomic numbers.
the periodic law revealed important analogies among the 94 naturally occurring . It stimulated renewed interest in inorganic chemistry and has carried into the present with the creation of artificially produced short-lived elements
It is easy to visualize the significance of and electronic configuration in periodicity of elements.
In fact it is now visualized that the periodic law is essentially the consequence of periodic variation in electronic configurations , which indeed determine the physical and chemical properties of elements of their .
