(Elements & Compounds) a very rare radioactive element that occurs in trace amounts in uranium ores. The isotopepolonium-210is produced artificially and is used as a lightweight power source in satellites and to eliminate static electricity in certain industries. Symbol: Po; atomic no: 84; hal...
Polonium is the heaviest element in the chalcogen family. It is in Group 16 (VIA) on the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. The other chalcogen elements are oxygen, sulfur, selenium, and tellurium. SYMBOL Po ATOMIC...
Polonium (Po or Element 84) is one of the radioactive elements discovered by Marie and Pierre Curie. This rare element has no stable isotopes. It's found in uranium ores and cigarette smoke and also occurs as a decay product of heavier elements. Although there aren't many applications for ...

The first two of these elements— polonium and radium—were discovered by Marie Curie (1867-1934) and Pierre Curie (1859-1906). The third, actinium, was discovered in 1899 by a close friend of the Curies, French chemist André Debierne (1874-1949). Debierne suggested the name actinium ...

The half-life of uranium-238 is4.5 billion years. It decays into radium-226, which in turn decays into radon-222. Radon-222 becomes polonium-210, which finally decays into a stable nuclide, lead. Marie Curie, who worked with uranium to discover several even more radioactive elements (poloni...
