Which types of materials have a molecular structure that makes them good conductors explain how understanding this relationship can help people design more efficient technologies

Metals

Explanation:

The metals are the conductors of electricity. These are made up of atoms which conducts electricity in the form of electrons in the outer shell that can move freely. These take away the electric charge on the entire metallic system. This way the metal conducts electricity and can also pass electricity to other surfaces if come in their contact. Thus the metals are used for creating equipment of technological importance.
