Question

Consider the following decay series:  What is the symbol for the product labeled as Y?

Quizplus · Accepted Answer

In a decay series, the symbol for the product labeled as Y will have the same parent as the product labeled as X and a mass number that is 4 less than the parent. Looking at the options, we can see that C has a parent with the same identifier (11ea7cbf_8f3a_1ef5_a2ab_430b4c230e8f_TB3246_00) as the X product and a mass number 4 less than the parent (4608, compared to the parent's 4612). Therefore, C is the correct choice.
