The Theory of Alpha Decay
... In the first formula, we have used that the α-particle is in fact the nucleus of Helium atom, which would have two electrons in its stable state. The double positive charge then indicates that only the nucleus appears on the right, and so leaves the daughter atom twice negatively charged. In nuclear ...
