They are electrons that are transferred through the conductor thanks to bonds of the atoms within the substance. An example of this kind of bond would be a metallic bond.

What happens to the electrons in a conductor when there is a potential difference between the conductor's ends?
The free electrons in a conductor will, when a difference of potential (voltage) is applied at its ends, participate in electron current flow (or just current, if you prefer). The voltage applied to the conductor will drive current through the conductor, and the free electrons will support current flow. These electrons will actually move through the conductor. As electrons are driven into one end of the conductor, the free electrons "shift over" and electrons stream out the other end of the conductor. This is the essence of current flow in conductors.
Why electron freely in a metal?
The term conductor is generally applied to a substance or material that has a lot of free electrons in it. The name conductor is applied because the free electrons are already there. A material does not have free electrons because it is a conductor, but is a conductor because it has a lot of free electrons. That said, let's look at what's going on. These free electrons have energies that permit them to "wander" through the conductor; they're not "locked into" the structure of the material. And when a voltage (potential difference) is applied, current flows through the conductor because the free electrons are moving. They're made to move by the applied voltage. If we take the case of a wire in a circuit, the wire is a conductor. This wire, say a copper one, has many free electrons in it, and when we apply a voltage, electrons move. The voltage forces electrons into one end of the wire, and the free electrons "shift over" and electrons emerge from the other end of the wire. This movement of free electrons in response to an applied voltage through an conductor is the essence of current flow in that conductor.

Why is alumium a good conductor?

Is nitrogen an electrical conductor?
No Nitrogen is a non-metal an is therefore a poor conductor of electricity because there is no where for the electrons to flow and there are no free electrons
Is metal a conductor of electricity?
For a material to conduct electricity, it must have free movable electric charges, such as free electrons or free ions, in order to 'carry' electricity. In the case of metals, there is a 'sea' of delocalized electrons. These free electrons can 'carry' the electricity, and thus, it is a conductor.

How is current prodeced?
Current is proceeded in a conductor by the activation and contact vibration of free electrons in conductor.
