Metals Good Conductors

Introduction to metals good conductors:

All the conductors shares a common property that they are able to carry the electric current to the voltage difference that is applied. The flow of electronic charge is called as electric current. Inside a material it is the electric field that forces all the free charges to move. So, there will be no electric field inside a conductor. If electric field exists inside a conductor then all the charges in the conductor doesn’t move.In most of the cases the majority of the electrons inside these materials are fixed at one place which are tightly held by an atom it its orbit. In all the conductors some of the electrons move and find their own way.

About good conductors of metals


Metals basically are a kind of elements. These elements are quite different because they lose electrons from the atom readily in order to form positive ions or cations which are highly stable. All the cations form metallic bonds between atoms of other metal.

All the existing metals conducts the electricity. Metals are used as good conductors of electricity and heat because the metals will have space in their valence energy band that is unfilled. The conduction electrons travel in different directions with a very high velocities when there is no electric field. The same thing also happens even at the cold temperatures such as absolute zero. When an electric field is applied then there will be some imbalance that is developed and the free electrons flows from the outer band. Due to defects present in the lattice, the scattering of electrons occurs and the resistance for conduction comes in metals.

Examples of metals good conductors:


Metals can be taken as a good example of the conductors of electricity. The good conductors of electricity are silver, copper and aluminum. Some other good conductors of electricity are iron, gold, mercury, steel, nickel, magnesium and sea water. Metals are not only good conductors of electricity but also a very good conductors of heat.
