Welcome to the final part (Part–5) of NCERT Curiosity Class 8 Science Chapter 8 – “Nature of Matter: Elements, Compounds, and Mixtures” 🔬

In this chapter-end session, we revise and solve all the “Keep the Curiosity Alive” and Exercise Questions that test your understanding of elements, compounds, and mixtures. Let’s strengthen your science concepts with clear explanations, reasoning, and practical connections!

🧠 Topics Covered:

Chapter End Exercise – Key Question Types:

🧩 A + B → C classification (element, compound, mixture)

💨 Assertion–Reason: Why is air a mixture?

💧 Water’s properties vs. constituent elements (Hydrogen & Oxygen)

✅ Correctly matched examples (mixtures, compounds, elements)

⚙️ Classify reaction products (Fe oxide, Mg oxide)

🔍 Classify substances into elements, compounds, and mixtures

🧲 Difference between heated iron-sulfur mixture and reaction product

🧬 Can a substance be both element and compound?

🌍 What if water were a mixture – how would life change?

🔥 Identify gas A (from reaction with acid test)

💡 Compounds made of non-metals and their uses

🪙 Why gold is both a mineral and a metal

Chapter Summary:

Matter exists as elements, compounds, and mixtures

Pure substances contain one type of particle

Mixtures can be separated physically, but compounds require chemical change

Importance of elements and compounds in industry, environment, and life
