Polonium is a rare, silvery-gray, radioactive, low-melting metalloid. Polonium readily reacts with dilute acids, but only slightly with alkalis. All of its isotopes are radioactive. 210Po emits a blue glow, as the air around it is excited by the decay products. 1 gram of Po emits as ...

Polonium is an extremely unstableradioactivechemical element which forms as part of the decay process ofradium, another radioactive element. Because polonium is a stage in radium's decay process, it is sometimes called radium F. This element appears in trace amounts in nature, typically inuranium...
Polonium (pronunciation: peh-LOW-nee-em) [3] is a rare, highly radioactive metalloid, classified as a Chalcogen [5] and represented by the chemical symbol Po [1, 2]. It has more than 25 isotopes, out of which Polonium-208, Polonium-209, and Polonium-210 are relatively long-lived [4...
