: The overall [[Electrical Charge|charge]] of the [[Universe]] is zero.
: If a [[Electrical Charge|charged]] [[subatomic Particle|particle]] comes into existence another [[subatomic Particle|particle]] with opposite [[Electrical Charge|charge]] must also come into existence.
: '''Conservation of charge''' can be applied to all [[Fundamental Interactions|fundamental interactions]] to balance the [[Nuclear Equation|equations]] and to ascertain the types of [[Subatomic Particle|particles]] produced.
