The significance of Mendeleev’s periodic table has to be described briefly

Concept Introduction:

In Mendeleev’s periodic table the elements were arranged by increasing number of atomic weight. Group of elements with similar properties were arranged together.

Mendeleev’s classification

In Mendeleev’s classification the elements were grouped according to their properties. Equal importance was given for the undiscovered elements; some gaps were left for the elements yet to be discovered.

Expert Solution & Answer

Explanation of Solution

In Mendeleev’s periodic table the elements were arranged by increasing order of atomic mass, group of elements with similar properties were placed in to vertical column in the table.

Mendeleev named eka-aluminium and eka-silicon for the undiscovered elements and predicted its properties, Gallium and Germanium were discovered and its properties matched the predicted properties of eka-aluminium and eka-silicon respectively.

Conclusion

The significance of Mendeleev’s periodic table was described briefly.
