Class 10 Science Solution [Chapter 3: Metals & Non Metals], READ HERE

Chapter 3 of the Class 10 Science textbook, Metals and Non-Metals, is an essential part of the Chemistry syllabus. It focuses on the physical and chemical properties of metals and non-metals, their uses, reactivity, and the differences between them. This chapter not only builds conceptual understanding but also forms the basis for higher-level studies in science and engineering.

KEY CONCEPTS COVERED

Physical Properties of Metals and Non-Metals: Metals are generally hard, lustrous, malleable, ductile, sonorous, and good conductors of heat and electricity. Common examples include iron, copper, and aluminum. In contrast, non-metals like sulfur, carbon, and phosphorus are brittle, dull, and poor conductors of heat and electricity (except graphite).

Chemical Properties: The chapter explains how metals react with air (oxygen), water, and acids, often forming oxides and releasing hydrogen gas. For example:

• Metal + Oxygen → Metal Oxide
• Metal + Acid → Salt + Hydrogen Gas

Non-metals typically do not react in the same way with acids, and their oxides tend to be acidic or neutral, whereas metal oxides are usually basic.

The Reactivity Series: A vital concept, the reactivity series ranks metals based on their reactivity. More reactive metals like potassium and sodium react vigorously with water, while less reactive metals like gold and platinum do not react easily.

Extraction of Metals: This section discusses how metals are extracted from their ores. The process varies depending on the metal’s reactivity – including methods like reduction with carbon, electrolysis, and refining.

Corrosion and Prevention: Metals like iron rust when exposed to moisture and oxygen. The chapter discusses how corrosion can be prevented using methods like painting, galvanization, and alloying.
