Polonium was discovered by
Madame Curie in 1898AD.
- as a trace component of pitchblende,
- as a breakdown product of the radioactive decay of radium
and is itself radioactive with a half-life of 138 days, and
- may be isolated from radon gas, which is used to treat
cancer in hospitals.
Polonium has similar chemical properties to Selenium
Polonium forms a hydride, PoH3, and several oxides are known,
PoO, PoO2 and Po2O3.
