10th Class Science Chapter – 3: Metals and Non-metals – PDF Free Download
At Ramsetu, we aim to provide educational resources that make learning engaging and comprehensive. Chapter 3, “Metals and Non-metals,” from the 10th Class Science textbook covers the physical and chemical properties of metals and non-metals, their reactions, and their uses. This chapter helps students understand the distinct characteristics of metals and non-metals and their significance in daily life.
Real-life applications and significance of metals and non-metals
Key Concepts and Definitions:
Metals: Elements that are typically hard, shiny, malleable, ductile, and good conductors of heat and electricity.
Non-metals: Elements that are generally brittle, non-lustrous, and poor conductors of heat and electricity.
Alloys: Mixtures of two or more elements, where at least one is a metal, to improve the properties of the constituent metals.
Chapter Content:
Summary of “Metals and Non-metals”:
Introduction to metals and non-metals and their importance.

Chemical Properties of Non-metals:
Reactions with oxygen (formation of oxides).
Reactions with acids and bases.
Alloys:
Definition and examples (e.g., brass, bronze, stainless steel).
Importance of alloys in improving metal properties.
Principles and Properties:
Reactivity Series: Arrangement of metals in order of decreasing reactivity.
Displacement Reaction: A reaction in which a more reactive metal displaces a less reactive metal from its compound.
Applications:
Use of metals in construction, transportation, electronics, and jewelry.
Use of non-metals in fertilizers, disinfectants, and insulating materials.
Industrial applications of alloys for enhanced strength and durability.
Frequently Asked Questions (FAQs):
What are the physical properties of metals?
Metals are typically hard, shiny, malleable, ductile, and good conductors of heat and electricity.
What is the reactivity series?
The reactivity series is an arrangement of metals in order of decreasing reactivity, which helps predict their reactions with other substances.
What are alloys and why are they important?
Alloys are mixtures of two or more elements, where at least one is a metal, used to improve the properties of the constituent metals, such as strength and resistance to corrosion.
