Conductivity of the atom depends on the number of electrons that are in the valence shell. When an atom has only one electron in valence shell, it is almost a perfect conductor. When an atom has eight valence electrons the valence shell is said to be complete and the atom is an insulator.

An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such as electricity or heat.

Conductors have more free electrons that are not aligned, once the voltage is applied they start conducting, but semiconductors don conducts til the threshold voltage is overcome. So conductors have more free electrons than others.

Free electrons and the energy gap between conduction and valence band is less so free electron easily goes to conductance band. And free electron means they are ready for action so potential energy applied they start conducting.

Basic think finally. Currents means flow of electrons.

As so many electrons mean more current flow. And conductor having more electrons compared to semiconductor and non conductor.

PRINCE said:   1 decade ago
Basically current is rate of flow of charges or electrons and conductors are those in which current flow so conductor is a material with lot of free electrons.

In an atom the free electrons are present at outermost orbit.It can easily flow from one atom to another by applying voltage. So it is called as conductor.

The Conductor has free electron unless a voltage is high and less current till free electron observed but work done will be done by the threshold voltage.
