Polonium is a very rare element in nature because of the short half-lives of all its isotopes. Nine isotopes, from 210 to 218 inclusive, occur in traces as decay products : 210 Po, 214 Po, and 218 Po occur in the decay chain of 238 U ; 211 Po and 215 Po occur in the decay chain of 235 U ; 212 Po and 216 Po occur in the decay chain of 232 Th ...
Some of polonium's applications relate to the element's radioactivity. For instance, polonium is used as an alpha-particle generator for research. Polonium alloyed with beryllium provides an efficient neutron source. Polonium is also used in nuclear batteries. Most polonium is used in antistatic devices.

Organopolonium chemistry describes the synthesis and properties of chemical compounds containing a carbon to polonium chemical bond.. As polonium is a highly radioactive element (its most commonly used isotope, 210 Po, has a half-life of about 138 days), organopolonium chemistry is mostly unexplored, and what is known is mostly confined to tracer-level studies due to self-destruction and ...
While it is the least theoretically studied of the 7p elements, its chemistry is expected to be quite similar to that of polonium. [4] The group oxidation state of +6 is known for all the chalcogens apart from oxygen which cannot expand its octet and is one of the strongest oxidizing agents among the chemical elements.

Polonium is a chemical element with the symbol Po and atomic number 84, discovered in 1898 by Marie Skłodowska-Curie and Pierre Curie. A rare and highly radioactive element, polonium is chemically similar to bismuth [44] and tellurium, and it occurs in uranium ores. Polonium has been studied for possible use in heating spacecraft.
Polonium-210 (210 Po, Po-210, historically radium F) is an isotope of polonium. It undergoes alpha decay to stable 206 Pb with a half-life of 138.376 days (about 4 + 1 ⁄ 2 months), the longest half-life of all naturally occurring polonium isotopes ( 210–218 Po). [ 1 ]
