Isotopes of actinium
text:
Actinium (89Ac) has no stable isotopes and no characteristic terrestrial isotopic composition, thus a standard atomic weight cannot be given. There are 34 known isotopes, from ⁰Ac to ⁶Ac, and 7 isomers. Three isotopes are found in nature, ⁵Ac, ⁷Ac and ⁸Ac, as intermediate decay products of, respectively, ⁷Np, ⁵U, and Th. ⁸Ac and ⁵Ac are extremely rare, so almost all natural actinium is ⁷Ac. The most stable isotopes are ⁷Ac with a half-life of 21.772 years, ⁵Ac with a h
