The formula determined by this method is called the empirical formula or simplest formula. You start with the electrostatic potential, where the bottom of the clouds were more negative, and then the ground is positive as well, and at some point, that potential energy turns into kinetic energy as the electrons transfer through the air, and then that gets converted into, or a good bit is going to be.
