Polonium, which eventually decays to an isotope of lead, is one of the more unstable points in this chain, unstable enough that there are some 33 known variants (isotopes) of the element.

Marie Curie. Wikimedia Commons. There are around 30 different isotopes of polonium ranging in atomic mass from 194 to 218, only differing from each other in their neutron number.

Polonium was first discovered by Marie and Pierre Curie in 1897. Polonium-210 is one of 25 radioactive isotopes of polonium. It decays to lead by alpha particle emission, with a half-life of 138 days.
