Charge conservation charge in a region and the flow of charge into and out of that region, given by a continuity equation between charge density formula_1 and current density formula_2. This does not mean that individual positive and negative charges cannot be created or destroyed. Electric charge is carried by subatomic particles such as electrons and protons. Charged particles can be created and destroyed in elementary particle reactions. In particle physics, charge conservation means that in reactions that create charged particles, equal numbers of positive and negative particles are always created, keeping the net amount of charge unchanged. Similarly, when particles are
Finn (given name) Finn (given name) Finn is generally regarded as a masculine given name. The name has several origins. In some cases it is derived from the Old Norse personal name and byname "Finnr", meaning "Lapp" or "Finn". In some cases the Old Norse name was a short form of other names composed with this element.
