Free electrons are bound to the conductor's lattice structure by electrostatic forces, preventing them from leaving. Additionally, the presence of positive nuclei within the lattice attracts the negative electrons, keeping them within the material. The random thermal motion of electrons within the conductor is not sufficient to overcome these forces and cause them to escape.

What is present in a conductor when an electrical charge moves through it?
In a conductor, free electrons are present that can move when an electrical charge is applied. These free electrons are responsible for the flow of current through the conductor.
When a voltage is applied to a conductor free electrons?
When a voltage is applied to a conductor, free electrons gain energy and move in response to the electric field created by the voltage. This movement of electrons constitutes an electric current flowing through the conductor.
What are free electrons of conductor?
First we have to define the word an electron, An electron is negatively charged particle. A metal is a substance consists of number of both electrons and protons. Electrons emitted from the metal surface through different ways such ways as Thermionic, Photoelectric, etc. Free electrons of conductor are electrons emitted from conductor when it disturbed through ways as mentioned above
What are free electrons in a conductor?
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. They're what cause the conductivity
What are Number of free electrons in good conductor in electricity?
Millions of free electrons
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?
Because it has free electrons
When a voltage is applied to a conductor free electrons?
When a voltage is applied to a conductor, free electrons gain energy and move in response to the electric field created by the voltage. This movement of electrons constitutes an electric current flowing through the conductor.
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.
Why is metal a conductor instead of insulator?
metal has free electrons
Why is metal not a good conductor?
Because they dont have free electrons.
