NCERT Grade 10 Science Chapter 3, Metals and Non-Metals, comes under the Theme of Materials. The NCERT Solutions for class 10 Science provided in this chapter are designed by our subject matter experts in an easy and simplified language. This chapter will help the students to classify the elements learned in Class IX into metals and non-metals on the basis of their properties. The solutions given for the problems will help to build a strong foundation for the students over which they can learn uses of metals and non-metals in day-to-day lives, categorising elements as metals and non-metals, relation of these properties to the uses of these elements. This includes Physical Properties under the two specific heads of metals and non-metals. The topics have been described with the help of practical activities and descriptive diagrams and practice-based questions. The solutions given to these questions further aids to build a strong concept for the learner.
The guided solutions are given for the topics Chemical Properties of Metals, What happens when Metals are burnt in Air? What happens when Metals react with Water? What happens when Metals react with Acids? How do Metals react with Solutions of other Metal, the reactivity series will help in the better reinforcement of the concept to the students.The topic How do metals and non-metals react has been explained to understand why do metals react in this manner. Simple tables to explain the electric configuration of some elements, explanatory diagrams and figures activities to be done in the Chemistry laboratory and solutions to the concept related questions shall strengthen your knowledge and help you to deal with complex problems further in the subject.
Chapter 3, Metals and Non-metals of NCERT Grade 10 Science will help you to understand the occurrence of metals and how metals can be profitably extracted from it in form of ores. Extraction of metals, extraction of ores, Extracting Metals Low in the Activity Series, Extracting Metals in the Middle of the Activity Series, Extracting Metals towards the Top of the Activity Series shall equip you more with the topic of extraction of metals. The topic refining of metals will be introduced that will help the students to understand how impurities are removed to obtain pure metals.
The topic of corrosion has also been explained in the Chapter 1. This solutions provided for this topic will help learners to investigate the conditions under which iron rusts. The topic prevention of corrosion will help the learner to understand how rusting of iron can be prevented.Chapter 3 is a part of Unit I, Chemical Substances-Nature and Behaviour and hold weightage of 25 marks in the final examination of Grade 10 according to the latest pattern.Get 100 percent accurate NCERT Solutions for Class 10 Science Chapter 3 (Metals and Non-metals) explained by expert Science teachers.
