Quick Revision Box: Metals & Non-Metals

  • Metals: Shiny, malleable, ductile, good conductors of heat & electricity, form basic oxides, lose electrons (electropositive).
  • Non-Metals: Dull, brittle, poor conductors (except graphite), form acidic oxides, gain electrons (electronegative).
  • Reactivity Series: K > Na > Ca > Mg > Al > Zn > Fe > Sn > Pb > H > Cu > Hg > Ag > Au > Pt
  • Metal + Acid: Metal + Acid → Salt + Hydrogen gas (for metals above H in series).
  • Metal + Water: Metal + Water → Metal hydroxide + Hydrogen (vigorous for K, Na; with steam for Fe, Zn).
  • Displacement Reaction: More reactive metal displaces less reactive metal from its salt solution.
    • Extraction of Metals:
  • Roasting: Sulphide ore + O₂ (heat) → Metal oxide + SO₂ (in excess air).
  • Calcination: Carbonate ore (heat) → Metal oxide + CO₂ (in limited air).
  • Reduction: Metal oxide + Carbon/CO/Al → Metal + CO₂/Al₂O₃.
  • Electrolytic Refining: Impure metal (anode), Pure metal (cathode), Metal salt electrolyte.
  • Corrosion: Oxidation of metals (e.g., Rusting: 4Fe + 3O₂ + xH₂O → 2Fe₂O₃.xH₂O).
  • Alloy: Homogeneous mixture of metals/metals & non-metals (e.g., Steel: Fe+C, Brass: Cu+Zn).
  • Amphoteric Oxides: React with both acids & bases (e.g., Al₂O₃, ZnO).
  • Aqua Regia: 1 part conc. HNO₃ + 3 parts conc. HCl; dissolves Au & Pt.

Chapter Summary: Metals and Non-metals

This chapter dives into the fascinating world of elements, categorizing them into metals and non-metals based on their physical and chemical properties. You'll explore why some elements shine while others don't, why copper conducts electricity but sulphur doesn't, and how these properties determine their uses in daily life—from kitchen utensils to electrical wires and jewelry.

Our MCQ platform is specifically designed to mirror board exam patterns and competitive test standards. We provide 130+ carefully graded questions—from basic recall to advanced application—covering every NCERT concept. By practicing here, you'll identify which metals react with steam but not cold water, predict displacement reactions correctly, understand why aluminium is called 'self-protecting', and memorize essential chemical equations. This targeted practice builds both conceptual clarity and exam-time speed, turning theoretical knowledge into confident, accurate answers. Our detailed explanations ensure you don't just memorize but truly understand why reactions occur, preparing you for any twist the examiner might introduce.
