Question

the following nuclei do not lie in the band of stability. how would they be expected to decay? justify your answer using the neutron-proton ratio

Answer 1

Solution.

If the neutron-proton ratio is high, then these nuclides contain an excess of neutrons. Such nuclides undergo beta ( -) decay, as the decay converts neutrons to protons. If the neutron-proton ratio is low, then these nuclides contain an excess of protons. Such nuclides undergo beta (+) decay or electron capture, as the decay converts protons to neutrons.
