Chapter 4 The world of metals and non-metals

CBSE Notes Class 7 Science Chapter 4 The World of Metals and Non-Metals

Materials around us can be classified into metals and non-metals based on their properties. This chapter helps students understand the differences between these two groups and their uses in daily life.

Students learn that metals are usually shiny, hard, and strong. They conduct heat and electricity and can be shaped into different forms. Examples include iron, copper, and aluminum. Metals are used in making utensils, wires, machines, and buildings.Non-metals are used in various applications such as making fertilizers, medicines, and fuels.

This chapter helps students develop a better understanding of materials and their importance in daily life. It also lays the foundation for learning more about chemistry in higher classes.
