Well, there is no movement of charged particles through the air then. The form of energy flowing through the air is not electricity but electromagnetic radiation. That can even flow through a vacuum where there are no charged particles, molecules, atoms, or any of the usual subatomic particles. As for electricity to flow through air without sparking – that can be done, although not often practically, and the
