A radioactive nucleus
$$_Z^AX$$ $$to$$ $${}_{Z - 1}B$$ $$to$$ $${}_{Z - 3}C$$ $$to$$ $${}_{Z - 2}D$$,
where Z is the atomic number of element X. The possible decay particles in the sequence are :
$$_Z^AX$$ $$to$$ $${}_{Z - 1}B$$ $$to$$ $${}_{Z - 3}C$$ $$to$$ $${}_{Z - 2}D$$,
where Z is the atomic number of element X. The possible decay particles in the sequence are :
- A$$beta$$$$-$$, $$alpha$$, $$beta$$+
- B$$alpha$$, $$beta$$$$-$$, $$beta$$+
- C$$alpha$$, $$beta$$+, $$beta$$$$-$$
- D$$beta$$+, $$alpha$$, $$beta$$$$-$$
