Polonium is a radioactive element that exists in two metallic allotropes. The alpha form is the only known example of a simple cubic crystal structure in a single atom basis, with an edge length of 335.2 picometers; the beta form is rhombohedral.olonium is a very rare element in nature because of the short half-life of all its isotopes. 210 Po, 214 Po, and 218 Po appear in the decay chain of 238U; thus polonium can be found in uranium ores at about 0.1 mg per metric ton (1 part in 10 10), which is approximately 0.2% of the abundance of radium.
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. 210 Po emits a blue glow, as the air around it is excited by the decay products.olonium is a rare, silvery-gray, radioactive low-melting metalloid.
