Question

How and why metals act as a good conductors of electricity ?

Answer 1

physical properties of different metals make them useful for different purposes. For example, copper is used for electrical wiring because it is a good conductor of electricity.

Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in metals can move through the metal, allowing metals to conduct electricity. Superconductors have little or no electrical resistance.
