MCQ
During a negative beta decay:
- AAn atomic electron is ejected.
- BAn electron which is already present within the nucleus is ejected.
- CA neutron in the nucleus decays emitting an electron.
- DA proton in the nucleus decays emitting an electron.
✓
Answer
- A neutron in the nucleus decays emitting an electron.
Explanation:
Negative beta decay is given as
$\text{n}\rightarrow\text{p + e}^-+\bar{\text{v}}$
Neutron decays to produce proton, electron and anti-neutrino.
