Given:
The chemical equation is shown in the question
To find:
The type of radioactive decay in the following reaction
Step-by-step explanation:
In the case of Gamma emission, no mass number nor atomic number changes of daughter nuclei compared to mother nuclei.
In the case of alpha emission, mass number changes by 4 and atomic no by 2 of daughter nuclei compared to mother nuclei.
In the case of beta emission, only the atomic number of daughter nuclei changes, and it changes by 1.
Here, the daughter nuclei's atomic number is more than 1 compared to the mother nuclei.
Hence, the given emission is Beta.
