What is the most likely decay for the Co-62 nucleus?

Question

Quizplus · Accepted Answer

Co-62 has an excess of neutrons and can decay via β- decay to increase the neutron-to-proton ratio. Positron emission (A) and proton emission (E) are unlikely since Co-62 is located in the middle of the chart of nuclides, and its decay would require a large amount of energy. Alpha decay (D) is also unlikely since Co-62 is not heavy enough to undergo alpha decay. Option B is not a recognized decay mode.
