Why True & False for Metals and Non-Metals?
How this format sharpens your conceptual clarity
🔵 Metals and Non-metals define the two great kingdoms of the periodic table — their properties underpin materials science, electronics, and biology.
✅ T/F tests physical properties (luster, conductivity, malleability), reactivity series, ionic bonding, and extraction of metals.
🎯 Hydrogen is a non-metal that produces H⁺ ions like acids — it is placed in Group 1 but is NOT a metal.

Key Takeaways — Metals and Non-Metals
Core facts for CBSE Boards & exams
1
Metals: lustrous, malleable, ductile, good conductors, solid (except Hg).
2
Non-metals: dull (except iodine), brittle, poor conductors (except graphite).
3
Reactivity series (top to bottom): K, Na, Ca, Mg, Al, Zn, Fe, Pb, H, Cu, Ag, Au.
4
Ionic bond: metal donates electrons (cation) to non-metal (anion).
5
Ore = mineral from which metal is profitably extracted; gangue = impurities in ore.
6
Corrosion = metal surface oxidised by moisture/air; alloys resist corrosion better.
