A conductor, or electrical conductor, is a substance or material that allows electricity to flow through it. In a conductor, electricalchargecarriers, usuallyelectronsor ions, move easily fromatomto atom when voltage is applied. Most metals like copper are considered good conductors, while nonmetals...
a. a poor conductor b. brittle c. malleable Copper: Copper is one of the metallic elements in the periodic table. Copper has an atomic number of 29. Copper is one of the earliest used elements in human history, with the earliest recorded uses being as far back as 8000 BC. Answer ...
