Periodic Classification of Elements Class 10 Notes
Chapter 5 Periodic Classification of Elements
Periodic classification of elements is the process of classifying elements into different classes. This strategy compares the characteristics of multiple items to group similar items and isolate unrelated items. This helps us understand how different compounds combine to form different elements.
Chapter 5 of NCERT notes for Class 10 Science is devoted to periodic classification of elements. Students coming for exams should pay attention to these topics. As a result, this will help students get more grades. It is also designed according to the latest NCERT program.

The classification of elements is required for a convenient and systematic study of the behaviour and nature of substances.
The modern periodic table is divided into 7 horizontal rows called periods and 18 vertical columns called groups.
s-and p-block elements are called representative elements.
In a period, the number of valence electrons increases on moving from left to right.
In a group, the atomic radii increase with an increasing atomic number from top to bottom.
