Question on: SS1 Physics - Atomic Structure and Radioactivity

Gamma decay involves the emission of high-energy electromagnetic radiation called gamma rays. Unlike alpha and beta decay, gamma decay does not change the atomic number or mass number of the nucleus. Gamma rays are emitted to release excess energy from an excited nucleus, transitioning it to a lower energy state. The emission of gamma radiation occurs alongside alpha or beta decay, but it does not involve the release of any particles. Therefore, the atomic number and mass number remain unchanged.
