Electrical Conductivity measures a material's ability to conduct electricity. Generally METALS conduct better than NON-METALS. For an element to conduct electricity, it must have free electron to move around. Therefore, the larger the atom the weaker its attraction is to the nucleus, allowing it to be free and to conduct electricity. first national bank of hampton iowa
