When electrons drift in a metal from lower to higher potential does it mean that all the free electrons of the metal are moving in same direction?
No, not all free electrons in a metal move in the same direction when there is a potential difference. While there is a net drift of electrons from lower to higher potential, the majority of electrons are still undergoing random thermal motion. The overall effect of the applied electric field results in a slight net movement, but this does not imply that every free electron is aligned in the same direction.
Do diamonds conduct electricity?
they don't conduct electricity: they have no free electrons. graphite, however, made of the same stuff as diamond (carbon) has a different structure, which means that it does have free electrons, and a lot of them. Therefore graphite is a good conductor of electricity.
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.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
What is the electromagnetic radiation that rips electrons off of atoms to produce free radicals called?
Ultraviolet radiation can rip electrons off the atoms to produce free radicals. However radiations of higher frequency can also have the same effect. The higher the energy of the photon of the electromagnetic wave, the easier it is for the photon to knock off electrons from an atom.

Are free electrons stable?
No. Free electrons are not stable.
What are Number of free electrons in good conductor in electricity?
Millions of free electrons
Which would cause most of the free electrons to move in a conductor to move in the same direction?
The presence of an electric field would cause most of the free electrons to move in the same direction within a conductor. The electric field exerts a force on the electrons, causing them to move in the direction of the field. This movement of electrons is what constitutes an electric current.
Do diamonds conduct electricity?

What are free electrons or delocalized electrons?
Free electrons or delocalized electrons are electrons in a material that are not bound to a specific atom or molecule. These electrons are able to move freely throughout the material, contributing to its electrical conductivity. Delocalized electrons are commonly found in metals and conductive materials.
What is the energy band in which free electrons exist?
Free electrons exist in the conduction band, which is the highest energy band in a material where electrons are free to move and conduct electricity.

What are the electrons that are free of atoms called?
Electrons. The particle name doesn't change just because it is a free electron. Free at last!
Free electrons are produced at the metallic electrode that?
Free electrons are produced at the metallic electrode that has atoms, that give up electrons, and become ions in solution.
Elements in the same group have similar properties because they have the same?
the same number of electrons needed to fill their octet, the same number of valence electrons,
What does the term free moving electrons mean?
delocalized electrons
