When a radioactive nucleus emits a gamma radiation then the mass number of atom is:
Correct answer: A. Remain same
- A. Remain same
- B. Increased by a factor 2
- C. Decreased by a factor 1
- D. Increased by a factor 1
Explanation
Gamma rays have no charge and no mass therefore atomic and mass number remains same. It carries very high energy. So option A is accurate.
