Quizplus · Accepted Answer

The change in the second to last digit of the first set of numbers in the first code suggests that a nuclear decay has occurred. The change in the last digit of the second set of numbers suggests that a beta particle (an electron or positron) was emitted, as alpha particles and protons typically do not cause this type of change. The change in the last digit of the third set of numbers suggests a minor change in energy level, which is consistent with a beta decay. Therefore, the best choice is B) a beta particle.
