Question 51

During a sequence of decays, a parent nucleus emits only alpha particles and beta-minus particles.

The combined mass number carried away by all the emitted particles is 12.

The combined charge number carried away by all the emitted particles is +4.

The parent nucleus has a mass number of 247 and an atomic number of 96.

a.
