Select the nuclide that completes the following nuclear reaction.

Question

Quizplus · Accepted Answer

In order to complete the nuclear reaction given, we need to identify the missing nuclide that will balance the atomic and mass numbers on both sides of the arrow. The atomic number on the left side is 53, which means the element is iodine (I). The mass number is 133, which tells us that the sum of protons and neutrons in the nucleus is 133. On the right side of the arrow, we see that the atomic number remains the same (53), but the mass number increases by 1, indicating that a neutron has been converted into a proton. The only choice that satisfies these conditions by having an atomic number of 53 and a mass number of 134 is D (11eb6533_800a_f014_b0a1_d5107bb17482_TB8248_11), which represents the nuclide iodine-134.
