In the conventional description of metals, the strongly interacting conduction electrons can be accurately represented as a gas of weakly … Webb(thing that electricity can go through) is made of atoms. Each atom has electrons in it. If you put new electrons in a conductor, they will join atoms, and each atom will spit out an electron to the next atom. This next atom takes in the electron and spits out another one on the other side.
