Exam-style question
Try this first
In a beta decay process, a neutron in a nucleus transforms into a proton, emitting a beta particle (electron) and an antineutrino. If the initial nucleus has a mass number of 14 and an atomic number of 7, what are the mass number and atomic number of the resulting nucleus?.
Model answer
What a good answer should say
- The resulting nucleus will have a mass number of 14 and an atomic number of 8.
Explanation
Why this works
This question tests the understanding of beta decay and conservation laws. The mass number remains unchanged, while the atomic number increases by 1 due to the transformation of a neutron into a proton.
