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
Alan (given name) is today Russia, and who were known to Classical writers in the 1st century CE. According to historian Bernard Bachrach, the Alans settled in parts of what is today France, including Brittany, in the Early Middle Ages. Bachrach stated that the use of forms of the name in given names, surnames, and place names, are evidence of the continued influence of the Alans on the Gaulish, Breton and Frankish peoples. The Breton name "Alan" can not be a direct loan from the ethnic name of the Alans (rendered as "Alānī" or "Halānī" in Latin, from Scytho-Sarmatian "*Al[l]ān-", derived from Old
