Answer: The gamma decay is represented below.
Step-by-step explanation:
Gamma decay is defined as the process in which an unstable nuclei gives off excess energy by a spontaneous electromagnetic process and thus releases
. These radiations does not carry any charge and are electrically neutral.
The chemical equation representing gamma decay process follows:

where,
= unstable nuclei
= stable nuclei
= gamma particle
Hence, the gamma decay reaction is given below.
