a) Study of chemistry is simplified and organized leading to easy access of data of the
elements.
b) It was possible to predict the atomic mass, some properties and other details of
elements which are yet to be discovered during the time of Mendeleev.
c) There is striking similarity between the periodic table constructed empirically by
Mendeleev and the modern periodic table based on electronic configuration and
nature of chemical bond.
d) Interpretation of trends and periodicities of properties of elements provide a clear
understanding and proof for atomic behavior.
e) It is possible to predict the properties of elements by considering the position of
elements in the periodic table. On the other hand properties of element helps us to
predict the position of an element in the periodic table.
