If a helium nucleus is converted into a helium ion with a charge of +1, how many electrons must be emitted in this process to allow for the conservation of charge?

What is the name of the theory invented by Richard Feynman to describe the electromagnetic eld, and which led to the discovery of the Feynman diagram?
