why are metals better conductors than electrolytes?explain...answer if sure?

Answer 1

Metals have free electrons that can travel from atom to atom. These would conduct the electricity in the metal.

Electrolytes conduct electricity by moving the ions the electrolyte contains. Ions, which are basically atoms, are much more massive that electrons. The effect: a given voltage (which exerts a force on charges) can move electrons at a better rate as compared to ions. (from Newton's laws of motion)

Assuming that the ions in the electrolytes have an average charge of 1 electron (most do), this would mean the ion is moving more slowly than the electron in the metal. With a given voltage, you have more charge per unit time with electrons . (Current = Charge / Time)

Finally, from Ohm's Law (Voltage =Current * Resistance) and rearranging it so we have only resistance on one side:

Resistance = Voltage/Current

Since the voltage is constant, and current is larger for electrons, the resistance is smaller for electrons, meaning metals have less resistance. Less resistance, better conductor.

Answer 2

Electricity is made of Fast and free moving electrons travelling frm higher potential to lower potential.
Metals are the elements consisting of the free electrons which move freely over the conductor because of which it has got the lustrous property.a pure metal is always homogenenous. Hence it good conductor of electricity.
Electrolytes consist of free ions some has +ve charge and some -ve.The electrolyte are not totally Homogeneous which is the major draw back for its conductive property Hence electricity is not homogenenous, it varies in electrolyte.

Answer 3

Dennis beat me to the and. Bingo Dennis. The conductivity of a material is decided upon the amount of charge it can transmit in a specific unit of time. Since the electrons travel faster than the ions, they are able to transfer more charge per unit time.
