Question

what are the advantages and disadvantages of modern periodic table

Answer 1

advantages.:
The table can be used to predict properties of elements, even those that have not been discovered. Columns (groups) and rows (periods) indicate elements that share similar characteristics. The table makes trends in element properties apparent. The table provides important information used to balance chemical equations.

disadvantages:
1.Hydrogen resembles both the alkali metals and halogens But it has been placed with the alkalis. 2.The lanthanides and actinides have not been placed in the main body of the table. 3.Place of Multivalent elements is not sure in the modern periodic table.

Answer 2

advantages are:-

1. The classification of elements is based on the atomic number, which is a more fundamental property.

2. It explains the periodicity of the properties of the elements and relates them to their electronic configurations.

3. The reason for placing isotopes at one place is justified as the classification is on the basis of atomic number.

4. The position of the elements that were misfits on the basis of mass number (anomalous pairs like argon and potassium) could be justified on the basis of atomic number.

disadvantages are ...

1.Hydrogen resembles both the alkali metals and halogens But it has been placed with the alkalis.

2.The lanthanides and actinides have not been placed in the main body of the table.

3.Place of Multivalent elements is not sure in the modern periodic table.
