Polonium Symbol Where is it Found Being extremely rare to exist naturally[1], it is found in traces in uranium ores. The process of extracting polonium can be costly[1]. When produced artificially in the nuclear reactor,Bismuth-210 is first formed through the bombardment of Bismuth-209 with ...
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...
