    Why the Periodic table of elements has been removed from Class 10 science textbooks?

    The Periodic table of elements, the beauty of the physical universe, has been removed from the Class 10 textbook and pushed forward to a higher grade.

    NCERT says this has been done to reduce the content load on students due to Covid 19 pandemic and "age appropriation".

    We can understand the Covid 19 pandemic situation. That situation has eased.

    Another point is "age appropriation". Is that not age-appropriate?

    Let us discuss this.

    There were many modifications in the periodic table from time to time and the modern periodic table is quite exhaustive and elaborate. NCERT might have taken a thorough view of the load that it is creating in class 10 and based on that has shifted it to classes 11 & 12.
    Even after that change, students will be learning about many elements in their classes 9 and 10 and once they get to know about a good number of elements then they can be exposed to the vast periodic table. NCERT and other agencies like that make changes from time to time to distribute the syllabus more proportionately between the different classes. In my view possibly that could be the reason for doing so.
    Knowledge is power.

    A continuous effort is to be made regarding the updates of the periodic table and during our school days dating back 1965, were taught regarding the existence of 102 elements but since discovery is a continuous process where sustained research is carried out to update the number of elements, it has now swelled up to 118.
    To understand the different elements with their details, NCERT authorities have reviewed the age criteria of the students for their better comprehension and now the periodic tables are available in the text books of class 11 so that they can understand different technologies such X - Ray diffraction, Bohr's Atomic Theory and other techniques in a realistic way. Such changes are made with the consultation of different experts and the final node is taken after the concurrence of the experts.

    In my opinion, what NCERT did is very correct. The periodic table is not a simple subject to understand and to understand the same a lot of fundamental knowledge in chemistry and physics is required. Why an element is placed in a particular group and how the electronic configuration of an element plays an important role in the properties of a material etc are also to be taught to have a better understanding of this classification. The changes that are being made by NCERT will be made only after thorough discussions among the academicians and other higher authorities I feel. Anyhow, the subject will be taught in the 11th class. A student in the 11th class may be able to understand the science behind it in a better way than a student in the 10th class.

    "Periodic table of elements" is one of the civilizational achievements. In this table, we can see that varied elements share common atomic structure and the diversity of elements is because of variations in their atomic numbers. This is the reality and the beauty of the physical universe, which can trigger thoughts of the young minds of the children, who pursue diverse streams (not only the science stream). You need not be a science student to know this basic understanding. By pushing forward this subject to higher grade is simply depriving the 10 class students of basic understanding of beauty of the universe.Hence,I strongly recommend the NCERT to bring back this "truth" to the 10 standard books.
