Question

What type of radioactive decay would be expected for the unstable nuclide  ?

Quizplus · Accepted Answer

The only particle that can be emitted from a nuclide to decrease the neutron to proton ratio is a beta particle (electron) emission (B). Alpha particle emission (A) would result in a daughter nuclide with too high a proton to neutron ratio. Positron emission (C) would also result in a daughter nuclide with too high a proton to neutron ratio. Gamma ray emission (D) and neutron emission (E) do not affect the neutron to proton ratio of the nuclide.
