Can Metals Conduct Electricity?

Yes metals can conduct electricity due to the mobile electrons throughout the structure. For example when you stick a metal instrument in an electrical socket, you automatically get shocked but to dislodge you from the shock a wooden stick is used or an object that does not conduct electricity. This is because the electric current from the socket comes into contact with something that can pass it along i.e a medium which is the spoon  and you were able to experience the shock because the electrons present in the spoon made a pathway for the current to pass and therefore you felt what was a shock . So metals can indeed conduct electricity

Yes to my knowledge all electrical wire is metal based. All electrical hook-up are metal based. Metal is a natural for electricity.
