Polonium is the one the radioactive elements in the periodic table. It belongs to the oxygen family. The element is chemically similar to Tellurium ans Bismuth and it is found in the Uranium ores. It is the silvery metal, rare in nature. However, the flammability of the element is still not much known. A we know that flammability can be defined as how easily an element can ignite or burn itself causing combustion. Moreover, no data concerning the flammability of the polonium is known.
