Electrostatic force
Oxidative stress is a term that describes the loss of electrons that can create free radicals. Free radicals are molecules with unpaired electrons that can damage cells by reacting with other molecules, leading to a chain reaction that destroys chemical bonds in the process.
No, covalent networks do not conduct electricity when solid because the electrons are tightly held in place between the atoms and are not free to move. This means that there are no free electrons available to carry an electric current.
Wood does not have any free electrons. wood is made by organic molecules (Compensation of carbon, Hydrogen and oxygen...etc). Their electrons are well bonded with their molecule's protons. So wood does not have any free electronics. Selvendra +91 9601293378
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.
Free electrons in a metal are called conduction electrons. These are loosely bound to the metal lattice and are able to move freely throughout the material, allowing metals to conduct electricity efficiently.

Free electrons most definitely repel each other. Any attempt to create a buildup of electrons in a specific spot will eventually result in the repulsion amongst these electrons to overcome the attempt to collect them. When you rub your skin against a wool rug on a dry day, you build up a surplus of free electrons on your skin. The repulsion between these free electrons cause this surplus to scatter to all parts of the skin, thus permitting a discharge of them to occur at any place in your skin.

No. Free electrons are not stable.
Well intrinsic semiconductor is semiconductor crystal with no impurities in it. In intrinsic semiconductor the electrons in valence band(valence electrons) gain energy(due to thermal enegry) and break free into conduction band(means it become free electrons). As this electron breaks free, a vacancy is created in place of it. It is called as a hole. This hole has a positive charge. So current in semiconductor is due to flow of this free electrons and holes. But this current is very small in magnitude. The difference between free electrons and valenece electrons is that valence electrons are often bonded to other atoms in crystal. But free electrons can freely move throughout the crystal.
Yes. just go on gamecenter website and find the create place.
An electric current goes through an electric circuit, if it is closed.
Electrons carry electric charge. When they move through a conductor, they create an electric current, which is the flow of electric charge. This flow of electrons is what powers electrical devices and enables the transmission of electricity.
Millions of free electrons

Physically all the electrons are similar.
