What is the balanced nuclear equation for the beta decay of Carbon-14?.
- A.14C -> 14N + 0e
- B.14C -> 14N + 1e
- C.14C -> 14N + 0β
- D.14C -> 14N + 1β
Model answer
What a good answer should say
- 14C -> 14N + 1e
Explanation
Why this works
In beta decay, a neutron in the nucleus of Carbon-14 is converted into a proton, emitting a beta particle (electron). The correct balanced equation shows Carbon-14 transforming into Nitrogen-14 with the emission of a beta particle.
