What happens to the mass number and the atomic number of an element when it emits gamma radiation?

Question

Quizplus · Accepted Answer

Gamma radiation is high energy electromagnetic radiation that does not have mass or charge. Therefore, it does not affect the mass number (number of protons and neutrons) or the atomic number (number of protons) of an element. The nucleus remains the same, but it becomes less energetic and more stable after emitting gamma radiation.
