NCERT Solutions for Class 10 Science Chapter 5 – Periodic Classification of Elements

Chapter 5 of the Class 10 Science NCERT textbook introduces students to one of the most profound and important discoveries or scientific feats in chemistry, which is the periodic table. The idea of a periodic table was to arrange the elements found in nature in a way that elements with similar properties can be grouped together. Many chemists at different points in history came up with different discoveries and ways of arranging elements.

The chapter discusses the major attempts by chemists in arranging these elements from Dobereiner’s triads, Newlands Law of Octaves, Mendeleev’s periodic table, and finally the Modern Periodic table that we use today.

Students will find this chapter to be very interesting and they should definitely give good attention to this chapter as the concepts learned here will be very useful in grades 11th and 12th.

10 Exercise Solution. Exercise Solutions

Exercise 5.1 – Early Attempts at the Classification of Tables

There are different types of elements in science. In segment 5.1 of Chapter 5 science Class 10, students will learn how these elements were classified on the basis of their properties of being gaseous, solid, metal, or non-metal.

  •  Section 5.1.1 – Dobereiner’s Triads

Johann Wolfgang Dobereiner was a German chemist. 5.1.1 of Chapter 5 science Class 10 covers his attempt of grouping elements based on their properties. On the basis of his segregation, groups called triads were formed. 5.1.1 exercise talks about triads.

  • Section 5.1.2 – Newland’s Laws of Octaves

Newland’s Laws of Octaves is an interesting section of the periodic classification of elements in NCERT Solutions for class 10 Science Chapter 5. It demonstrates how every 8th element, when the elements are arranged in ascending order of their atomic masses, has properties similar to the 1st one. This law is quite important from an examination point of view. So, students must go through it carefully and understand it thoroughly. 

Exercise 5.2 – Mendeleev’s Periodic Table

In exercise 5.2 of NCERT Solutions for class 10 science Chapter 5, Mendeleev’s Periodic Table is provided. As per this table, elements were classified based on their increasing atomic masses.

  • Section 5.2.1 – Achievements of Mendeleev’s Periodic Table 

Exercise 5.2.1 of NCERT Solutions class 10 science Chapter 5 highlights the achievements of Mendeleev’s periodic table. It displays how the existence of certain elements like Germanium (Ge), Gallium (Ga), and Scandium (Sc) was predicted even before they were discovered. 

  • Section 5.2.2 – Limitations of Mendeleev’s Periodic Table

Just like everything else, Mendeleev’s Periodic Table came with its set of limitations. As conveyed in Exercise 5.2.2 of class 10 science Chapter 5 NCERT Solutions, the table has no mention of Isotopes. Additionally, in this table, Hydrogen does not have a fixed position. Furthermore, Mendeleev’s table has no explanation for the irregular increase of atomic masses which made it hard to predict the number of elements discovered between two elements.

Exercise 5.3 – Modern Periodic Table

In Modern Periodic Table of class 10 science Chapter 5 NCERT Solutions, elements are arranged as per their increasing atomic masses. Students must learn the order of elements using smart tactics & techniques as provided by Extramarks.

  • Section 5.3.1 – Position of Elements in the Modern Periodic Table

Exercise 5.3.1 of class 10 science Chapter 5 solutions is all about Position of Elements. This periodic table comprises 7 periods and 18 groups, all of them segregated on the basis of maximum electrons present in the elements.  

  • Section 5.3.2 – Trends in the Modern Periodic Table

The Modern Periodic Table consists of many trends. From Class 10 Science Chapter 5 Solutions, students can expect to learn about electronegativity, electron affinity, metallic character, atomic radius, atomic size, and more.
