NCERT Class 10 Science Chapter 5: Chapter Description

In this chapter, students will learn how elements have been classified based on their properties and organised in the modern periodic table. They will study Döbereiner’s Triads and Newlands’ law of Octaves and their limitations.

Students will also learn how Mendeleev developed the modern periodic table based on atomic masses and how it was modified based on Moseley’s suggestion that physical and chemical properties of elements are periodic functions of their atomic numbers. Furthermore, the chapter also includes information about trends in atomic size, valency and physical and chemical properties of elements across the Modern Periodic Table.

Once students get their hands on NCERT Solutions for Class 10 Science Chapter 5 (Periodic Classification of Elements), they are advised to solve Class 10 Science Periodic Classification of Elements sample questions on Embibe. These are are available for free along with detailed solutions and will definitely help students ace this chapter easily.
