Question

Quizplus · Accepted Answer

Beta decay involves the emission of a beta particle (an electron) from the nucleus. This causes the atomic number of the nucleus to increase by 1, while the mass number remains the same. Looking at the options, we see that the only one that satisfies these criteria is option B. The original nucleus has an atomic number of 43 (TB) and a mass number of 85, and the product has an atomic number of 44 (RU) and a mass number of 85, which fits the process of beta decay.
