  • Physical properties
  • Shining surface (in pure state) [called metallic lustre]

  • Malleable [i.e. can be made thin sheets by beating]
  • Ductile [i.e. can be drawn into thin wires]
    • [Gold → Highly ductile]
  • Good conductors of heat
  • High melting point
  • Conduct electricity
  • Produce sound [some metals; these are called sonorous]

  • Non-metals are found in all the three states i.e. solid, liquid and gas, at room temperature.
