Which of the following particles is emitted from the nucleus during a decay?
Answer
β particle (electron)
The correct answer is β particle (electron) — Select the option that lists the electron as the emitted particle.
Step-by-step solution
- Recall that in decay a neutron inside the nucleus transforms into a proton, emitting an electron and an antineutrino.
- Identify the charged particle emitted: it is the electron, commonly referred to as the beta particle.
- Select the option that lists the electron as the emitted particle.
Common mistake: Confusing the beta particle with the neutrino or gamma ray.
Concept tested: Beta decay emission
