Explore: Polonium

Polonium is a chemical element; it has symbol Po and atomic number 84. A rare and highly radioactive metal (although sometimes classified as a metalloid)

Polonium-210 (210Po, Po-210, historically radium F) is an isotope of polonium. It undergoes alpha decay to stable 206Pb with a half-life of 138.376 days

There are 42 known isotopes of polonium (84Po), all radioactive, stretching from 186Po to 227Po. The isotopes 210 through 218 occur naturally in the four

chalcogen polonium. Livermorium is calculated to have some similar properties to its lighter homologues (oxygen, sulfur, selenium, tellurium, and polonium), and

won the 1911 Nobel Prize in Chemistry for her discovery of the elements polonium and radium, using techniques she invented for isolating radioactive isotopes

sulfur (S), selenium (Se), tellurium (Te), and the radioactive elements polonium (Po) and livermorium (Lv). Often, oxygen is treated separately from the

level of polonium inside his body when he died. The investigation ruled out HIV or any other infectious disease as a cause of death. The polonium was found

Polonium tetrabromide, is a bromide of polonium, with the chemical formula PoBr4. Polonium tetrabromide can be formed by the direct reaction of bromine
