Question

Quizplus · Accepted Answer

When a nucleus absorbs a neutron and emits a gamma ray, its mass number increases by one (due to the addition of a neutron) but its atomic number remains unchanged (since a gamma ray does not alter the number of protons). Therefore, the product nucleus will have the same atomic number but a mass number increased by one, making option D ("⁷⁶As") the correct answer.
