* Silver-31 is extremely unstable and short-lived. It decays primarily through proton emission, a rare type of radioactive decay where a proton is ejected from the nucleus.
* Positron emission occurs when a proton in the nucleus converts into a neutron, releasing a positron (the antiparticle of an electron) and a neutrino. This typically happens in isotopes with a high proton-to-neutron ratio.
The decay scheme of Silver-31 is:
³¹Ag → ³⁰Ni + ¹p + energy
Therefore, Silver-31 does not emit positrons.
