Question

If the neutron-to-proton ($n/p$) ratio of a radioactive nucleus is too high, placing it above the zone of stability, the nucleus will most likely tend to achieve stability through the primary emission of:

Prashant Kotian · Accepted Answer

Correct answer: B. A nucleus positioned above the stability belt has an excess of neutrons. To lower its ratio and enter the stability belt, a neutron decays into a proton and an electron. The electron is emitted from the nucleus as a -particle ().
