CBSE Science Periodic Classification of Elements Class 10 MCQ with Answers

Chapter 5 entirely focuses on how elements are classified to form periods and groups by following their atomic numbers. It explains the tabular method that developed in due course of time where elements with similar physical and chemical properties can be arranged. Scientists and chemists have discovered the patterns of repeating physical and chemical properties among specific elements.

To understand it better and theorise the concept, they have tried to make new groups of elements by carefully observing their properties. It is the observation and outcomes for decades that led to the foundation of the modern periodic table. Let us check the topics covered in this chapter first.

• Attempts to classify elements and their limitations

• Different laws of periodic classifications of elements

• Modern Periodic Law

• Trends in the Modern Periodic Table

• Electronic configuration, etc

These topics form the base of organic and inorganic chemistry as we can easily conclude the physical and chemical properties of elements from the periodic table. To develop your concepts, study this chapter well and then solve the CBSE Class 10 Science Chapter 5 Periodic Classification of Elements MCQs.
