A conductor is a material which allows electricity, heat or sound to flow through it. An electrical conductor conducts electricity. The ability to conduct electricity is called electrical conductivity. An excellent electrical conductor has high conductivity and low resistivity. Electrical resistivity is the reciprocal/opposite of conductivity.

The sodium and chloride ions actually separate in water, turning solid NaCl into Na+ and Cl- ions that can move freely through the solution. Electrons are one form of charge carriers and the most common, being that they have a net negative charge and are mobile inside of metals but free ions moving around in a solution also constitutes a current.

Gold is the most malleable metal. Credit: Buzzle. In contrast, ductility is the ability of a solid material to deform under tensile stress. Practically, a ductile material is a material that can easily be stretched into a wire when pulled as shown in the figure below. Recall pulling is applying tensile stress.
