  • Metals are ductile (can be drawn into thin wires) - Gold is most ductile (2km wire from 1g gold)
2

Chemical Properties of Metals

  • Metals react with oxygen to form basic metal oxides
  • Metal oxides are basic in nature and turn red litmus blue
  • Some metal oxides like Al₂O₃ and ZnO are amphoteric (show both acidic and basic properties)
3

Reactivity Series of Metals

  • Arrangement of metals in decreasing order of reactivity
  • Order: K > Na > Ca > Mg > Al > Zn > Fe > Pb > H > Cu > Hg > Ag > Au
  • Metals above hydrogen can displace hydrogen from dilute acids
4

Chemical Properties of Non-metals

  • Non-metals react with oxygen to form acidic or neutral oxides
  • Non-metal oxides are generally acidic and turn blue litmus red
  • Non-metals do not react with water under normal conditions
