What is electricity made out of?

I figured since it goes through wires, that there has to be some kind of atoms, but what kind? Is it a chemical? Are there even atoms moving though or just electrons? If it is electrons, where do they come from?

This is for wall outlet type electricity. I know it's a plasma, but that's about it.

Electricity is the motion of electrons. Plasma is the motion of entire atoms.

Think of a copper wire as a pipe, but electrons move through the space between atoms instead of water flowing through the pipe. Voltage is the driving force causing the electrons to move, much like a difference in pressure causes the water to move. Electric current is the flow rate of electrons moving through the wire.
