Answer
Identifying each of the following as alpha decay, beta decay, positron emission, or gamma emission:
Work Step by Step
Nuclear reaction ‘a’ shows that a positron (the radiation with +1 electric charge and 0 mass) has been emitted.
Nuclear reaction ‘b’ shows that a beta particle (β; the radiation with -1 electric charge and 0 mass ) has been emitted.
Nuclear reaction ‘c’ shows that astatine (At) has broken down and emitted an alpha particle (is similar to He with a mass number of 4 and atomic number of 2).
