The type of nuclear decay an unstable nucleus will undergo depends on its ratio of neutrons to protons. The radioisotope cobalt- 65 has a ratio of neutrons to protons of 1.41, which is too high for a nucleus of this size. What nuclear changes could reduce this ratio? Choose one or more: an increase in the number of protons a decrease in atomic number conversion of one or more protons to electrons removing electrons from the valence shell conversion of one or more neutrons to protons
