As I understand it electricity is the flow of delocalised electrons, so where do they come from in the first place?
In: Chemistry
[Delocalized_electron](https://en.wikipedia.org/wiki/Delocalized_electron) is just elections that have an orbit that is not associated with a single atom or a pair of atoms. They are created when atoms form together and crate bound between them. In a molecule, if it is not a covalent bond they are delocalized.
So if you for example have a ring of carbon with 6 atoms and 6 hydrogens on the outside you have Benzene. The elections that are involved in the bonds between the carbon can move around between multiple atoms.
For metal, the electrons that move around like that are a part of how the atoms are connected together.
So electrical generators do not create delocalized electrons they existed in the metal when it was formed. The is the reason the metal can conduct electricity.
The generator uses a magnetical field to create an electrical field. An election has a charge and will move in an electrical field. So the elections that can move in the metal are the delocalised electrons that already existed there.
