Electrical Conductivity

  • Metals have free electrons available to move and carry charge throughout the metal lattice structure.
  • Electrons entering one end of the metal cause a delocalised electron to displace itself from the other end.
  • Hence electrons can flow so electricity is conducted.
  • Copper is used extensively in the production of electrical wiring due to its excellent malleability and electrical conductivity.

Thermal Conductivity

  • Similarly, metals are also good conductors of heat.
  • The delocalised electrons are free to move and can also carry thermal energy throughout the metal lattice structure.
  • Some metals are better conductors of heat energy than others.
