Zinc has an atomic number of 30, meaning it has 30 protons. The isotope mentioned has 36 neutrons, so its mass number is 30 (protons) + 36 (neutrons) = 66. When it captures a proton, its atomic number increases by 1 (to 31), becoming gallium, and its mass number increases to 67. However, the product isotope's mass number is not directly given in the options, but since capturing a proton changes the element to the next one in the periodic table (from zinc to gallium) and the mass number increases by 1, the correct answer is gallium-66, which accounts for the original mass number before capturing the additional proton.
