Class 10 Science — Chapter 3: Metals and Non-metals
66 practice questions · 22 Easy · 22 Medium · 22 Hard
Practise Class 10 Science Chapter 3, "Metals and Non-metals", with 66 NCERT-aligned multiple-choice questions. The set is split into 22 Easy, 22 Medium and 22 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams and the JEE & NEET foundation years.
"Metals and Non-metals" is one of the chapters where concept clarity across physics, chemistry and biology basics really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Metals and Non-metals, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 10 Science mastery score. A few sample questions are shown below; sign in free to practise all 66.
Key concepts: Metals and Non-metals (Class 10 Science)
This chapter compares the physical and chemical properties of metals and non-metals, the reactivity series, and how metals are extracted and protected.
- Physical properties
- Metals are malleable, ductile, lustrous and good conductors; non-metals are generally the opposite (brittle, dull, poor conductors).
- Chemical properties
- Metals lose electrons to form positive ions and basic oxides; non-metals gain electrons to form negative ions and acidic oxides.
- Reactivity series
- K > Na > Ca > Mg > Al > Zn > Fe > Pb > (H) > Cu > Ag > Au. A more reactive metal displaces a less reactive one from its salt.
- Ionic compounds
- Formed by transfer of electrons; high melting points; conduct electricity in molten or aqueous state.
- Extraction of metals
- Method depends on reactivity: roasting (sulphide ores), calcination (carbonate ores), then reduction; very reactive metals by electrolysis.
- Corrosion & prevention
- Metals corrode (e.g. rusting of iron); prevented by galvanisation, painting, oiling or alloying.
Key formulas — Metals and Non-metals
💡 Exam tips for Metals and Non-metals
- Use the reactivity series to predict both displacement reactions and the extraction method.
- Aqua regia (3:1 conc. HCl : conc. HNO₃) can dissolve gold and platinum.
Sample questions
