Rationale for change
QID 403330:
The question stem gives two elements that are related through a decay process and asks which process would have led to this decay. In this case recognizing the isotopic notation change involves a change in mass number of 4, and a change in atomic number of 2, should be both a giveaway that it is alpha decay as well as that it has given off a helium-4 nucleus in this decay process.
The correct answer requires both the recognition that the process in question is alpha decay, as well as specifically knowing that a helium-4 nucleus is given off along the way.

This is an example of {{c1::alpha}} decay.
