I think there is no known physical theory that predicts the radioactive properties of elements in the periodic table. I guess it would be great if we can predict theoretically the radioactive properties (stability, fission-ability, half-life, types of emitted particles, and their energies ) given the number of neutrons and protons in the nucleus.
Given the number of neutrons and protons in a nucleus of an element, Can quantum theory predict all radioactive properties of that element (stability, fission-ability, half-life, types of emitted particles, and their energies)?
