Law of Conservation of Charge Charge can neither be created nor destroyed it can only be transferred from one place to another. q = Constant

Another Form q i = q f Any process occurring in an isolated system the net initial charge must be equal to the net final charge.

Applications of the Law Annihilation of Matter Electron and anti-electron (positron) when come close together, the two particles may annihilate one another. All their rest mass energy converts into radiant energy. The net charge is zero before and after the event. e- + e+  + 

Applications of the Law Decay of 0 0 is an uncharged particle. It decays into two gamma rays 0  + 

Applications of the Law Decay of Neutron Neutron (q= 0) decays into proton (q= +e), an electron (q= -e)and another neutral particle, a neutrino (q= 0). n p + e- + 

Applications of the Law Fusion of Deuterium (Heavy Hydrogen) Deuterium nucleus contains one proton and one neutron and has a charge of +e. Tritium contains one proton and two neutrons and also have a charge of +e. 2H + 2H 3H + p 2H + 2H 3He + n
