What is the law of conservation of electric charge?

Law of Conservation of Electric Charge: An isolated system's net electric charge never changes during a process (is conserved).

Total charge before and after are equal.

If there is any exchange or transfer of electric charge between an object and another in the isolated system, then the total number of charge is always the same within the system. Alternatively, the total number of Coulombs will always be the same.

This is an illustration of how electric charge conservation occurs during radioactive decay.

Electric charge is conserved because the amount of charge present before decay is 92e, and this is equal to the amount of charge after the decay (90e + 2e = 92e). 92U238 (parent atom) -------> (decays) 90U234 (daughter atom) + 2He4 (alpha particle).

The law of conservation of electric charge states that the total electric charge in an isolated system remains constant over time. In other words, electric charge cannot be created or destroyed, only transferred from one object to another.
