Question

A uranium nucleus (atomic number 92, mass number 231) emits an alpha-particle and the resultant nucleus emits a beta-particles. What are the atomic and mass numbers of the final nucleus? .

Answer 1

Answer:

Release of a alpha will decrease the atomic number by 2 and mass number by 4, and Beta particle will increase the mass number by 1 without change in mass number...

So, final product will have a mass number of 234 and atomic number = 91
