Barium - 141 is a beta emitter. What is the daughter nuclide that is produced when barium - 141 undergoes beta emission?

Question

Quizplus · Accepted Answer

Barium-141 undergoes beta emission, which means a neutron in the nucleus decays into a proton and an electron. The atomic number of the daughter nuclide increases by 1, while the mass number remains the same. Therefore, the daughter nuclide of barium-141 is lanthanum-141 (La-141).
