The answer is (2) Copper. Because copper is consist of atom. If it is decomposed, the atom will be changed. While chemical change is just the break down and form of chemical bonds between atoms.
Small ions have small areas. There is less resistance as they move through the solution.
For example, in molten salts, the conductivity of <span>Li+</span> is greater than that of <span>Cs+</span>.
Small ions have high charge density.
