"This condition results from the statistical distribution of the ions around each other considering the attractive tendency of oppositely charged particles and the repulsive tendency of similarly charged particles. Consequently, there is a statistical limit of the size of the volume element to which it applies. At the extreme, a volume small enough to contain only a single ion obviously cannot be electrically neutral. "
