Question
What changes occur in the nucleus of a radioactive element when it emits gamma radiation? Give one example, in support of your answer.
Solution
When the nucleus of a radioactive element emits gamma radiation, there is no change inside the nucleus except that its excess energy is released in the form of y-radiation.
Example: \[\ce{_Z^AZ -> _Z^AZ + γ}\]
The star indicates the excited state of nucleus.
