Detailed Solution

  • Metals are good conductors of electricity due to the presence of free electrons. 
  • The electrons that are not bound within the atom and are free to move are called free electrons
  • These free electrons move easily through the metal and allow the metal to conduct an electric current.
  • Rubber, plastic and wood do not possess free electrons and so cannot conduct electricity.
  • Copper is a metal and has free electrons which help in conduction of electricity, So it is a good conductor of electricity.
