NCERT Solutions for Class 10 Science, Chapter 3 - Metals and Non - Metals

In this chapter, you’ll learn about Metals and Non-Metals and various properties related to these. Metals such as gold, silver, copper, iron, aluminium are those elements that possess certain features like being hard, shiny, ductile, fusible, malleable, etc. Non-
metals such as coal, iodine, chlorine, sulphur are those elements that do not possess
features like being hard, shiny, malleable, ductile, fusible, etc. Metals are widely used in
making utensils, automobiles, light bulbs, coins, jewellery, industrial parts, water
boilers, electrical wires and more. Whereas, non-metals are used in water purifiers,
fertilizers, medicines, crackers and more.

An in-depth study of NCERT Solutions for Class 10, Chapter 3 – Metals and Non-Metals is important, as a thorough knowledge of metals and non-metals will help you
understand the properties of these elements in a better way.

In Class 10 Science Chapter 3, you will learn – 

Section 3.1 – In this section, you’ll study various physical properties of metals and non-
metals such as the hardness, malleability, ductility, sonority. You’ll also learn some
exceptions to the rule of these properties.

Section 3.2 – In this section, you’ll learn about various chemical properties of different
metals with the help of chemical reactions and chemical equations.

Section 3.3 – In this section, you’ll observe general properties for ionic compounds
based on their physical nature, melting and boiling point, solubility and conduction of
electricity.

Section 3.4 – In this section, you’ll learn how metals are extracted from ores. You’ll also
learn about categorising the metals based on their reactivity and different techniques
used for extracting pure metals from ores.

Section 3.5 – In this section, you’ll learn what corrosion is and various techniques to
prevent corrosion such as painting, oiling, greasing, chrome plating, galvanising,
anodising or making alloys.

In this chapter, you are provided with several activities and examples with their
solutions for a clear understanding of Metals and Non-Metals. To know more about
