Class 10 Chemistry Worksheet – Metals and Non Metals

Chemistry is a fascinating subject that helps us understand the materials we use in our daily lives. One of the most interesting chapters in Class 10 Chemistry is “Metals and Non-Metals.” This chapter dives into the properties, reactions, and uses of these two broad categories of elements, which form the foundation of the material world around us.

To aid students in understanding and mastering this topic, worksheets play a crucial role. They provide practice, reinforce concepts, and prepare students for exams. Below, we will explore the key concepts of the chapter, followed by an overview of what a worksheet on Metals and Non-Metals might include.

Introduction to Metals and Non-Metals

Metals and non-metals are two categories of elements that have distinct physical and chemical properties. These differences are important because they determine how these elements are used in various industries and applications.

Metals

Metals are elements that are typically hard, shiny, and good conductors of heat and electricity. Examples include iron, copper, aluminum, and gold. They have the following properties:

1. Physical Properties of Metals
   • Malleability: Metals can be hammered into thin sheets (e.g., aluminum foil).
   • Ductility: Metals can be drawn into wires (e.g., copper wires).
   • Conductivity: Metals are excellent conductors of heat and electricity.
   • Luster: Metals are shiny and reflect light.
   • High Melting and Boiling Points: Most metals have high melting and boiling points.
2. Chemical Properties of Metals
   • Reactivity with Oxygen: Metals react with oxygen to form metal oxides, which are usually basic.
     Example: 4Na+O_2​→2Na_2​O
   • Reactivity with Water: Some metals react with water to form metal hydroxides and release hydrogen gas.
   • Reaction with Acids: Metals react with acids to produce hydrogen gas.
     Example:
     $\text{Zn} + 2 \text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2$

     Zn+2HCl→ZnCl₂​+H₂​

Non-Metals

Non-metals, on the other hand, are elements that lack metallic properties. Examples include sulfur, carbon, and oxygen. They have the following properties:

1. Physical Properties of Non-Metals
   • Brittleness: Non-metals are brittle and cannot be hammered into sheets or drawn into wires.
   • Poor Conductors: They are poor conductors of heat and electricity (except for graphite).
   • Non-Lustrous: Non-metals do not have a shiny appearance.
2. Chemical Properties of Non-Metals
   • Reactivity with Oxygen: Non-metals form acidic or neutral oxides.
     Example:
     $\text{C} + O_2 \rightarrow \text{CO}_2$

     C+O₂​→CO₂​

   • Reaction with Water: Non-metals generally do not react with water.
   • Reaction with Acids and Bases: Non-metals show varied reactivity with acids and bases.
