List some of the advantages of the modern periodic table.
Some advantages of the modern periodic table are as follows:-
1. The table is based on a fundamental property i.e. atomic number of the elements.
2. It correlates the position of the element with its electronic configuration clearly.
3. The completion of each period is more logical. Across a period as the atomic number increases the energy shells are gradually filled up until an inert gas configuration is reached.
4. It is easy to remember and reproduce.
5. Each group is an independent group and the idea of sub-groups has been discarded.
6. The position for all isotopes of an element is the same since the isotopes have the same atomic number.
7. The position of the eighth group (in Mendeleev‘s table) is also justified in this table. All transition elements have been brought in the middle as the properties of transition elements are intermediate between the left and right portions of elements of the periodic table.
8. The table completely separates metals from non-metals. Metals are located on the left of the periodic table, and nonmetals are located on the upper right. They are separated by a diagonal band of semimetals.
9. The position of certain elements which were earlier misfit (interchanged) in Mendeleev’s periodic table is now justified because it is based on an atomic number of the elements.
10. Justification has been given for placing lanthanoids and actinoids at the bottom of the periodic table.
