An atomic nucleus having low \(n / p\) ratio tries to find stability by
- A the emission of an \(\alpha\) -particle
- B the emission of a positron
- C capturing an orbital electron (K-electron capture)
- D emission of a \(\beta\) -particle
Answer & Solution
Correct Answer
(B) the emission of a positron
Step-by-step Solution
Detailed explanation
Emission of a positron results in the conversion of a proton into neutron, along with the release of neutrino. Thus, the number of protons decreases and of neutron increases, i.e. \(n / p\) ratio increases and the nuclei becomes stable.
