Heavy nuclides with too few neutrons to be in the band of stability are most likely to decay by what mode?
Anarel [2989]

Answer:

Positron emission

Explanation:

In positron emission, a proton transforms into a neutron. This alteration results in a daughter nucleus with its mass number increased by 1, while the atomic number remains unchanged. The formation of a new neutron boosts the neutron count in the daughter nucleus, thus enhancing the N/P ratio.

Concurrently, a positron is emitted along with an anti-neutrino to ensure spin conservation.
