When do metals conduct electricity

Metals contain free moving delocalized electrons. When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side. Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them.

This then continues and passes the energy from the hot end down to the colder end of the substance. The electrons in metal are delocalised electrons and are free moving electrons so when they gain energy heat they vibrate more quickly and can move around, this means that they can pass on the energy more quickly. Silver has a larger atomic radius pm than gold pm , despite the fact that gold has more electrons that silver!

For a reason for this see the comment below. In column 11 of the periodic table, all of these elements copper, silver, and gold have a single s-orbital electron outer shell electron platinum does also, in column In general this means that it doesn't take much energy to knock an electron off temporarily, or add one temporarily. The specific electron affinities and ionization potentials are varied, and concerning conduction, having relative low energies for these two criteria is somewhat important.

Low resistance, free electrons, efficient See more below. Explanation: Metals conduct electricity well because they have a very low resistance that decreases the difficulty that there is for the current to pass through them around 0.
