Question

What is the basic difference in approach between the Mendeleev's periodic Law and modern periodic law

Answer 1

Answer:

we see that the basic classification change from atomic weight to atomic number is the basic difference in approach between Mendeleev periodic table and modern periodic table Mendeleev periodic law is based upon atomic weights of elements where as modern periodic law is based upon atomic number of elements

Answer 2

Answer:

• Mendeleev’s Approach for periodic law

Chemical properties and Physical properties of the elements are the periodic functions of the atomic mass of the corresponding elements.

• Modern approach for the periodic law

Chemical properties and Physical properties of the elements are the periodic functions of the atomic numbers of the corresponding elements.
