Polonium Definition, Symbol, Properties, Uses, & Facts

WebPolonium is a very rare natural element. It is found in uranium ores but it is uneconomical to extract it. It is obtained by bombarding bismuth-209 with neutrons to give bismuth-210, which then decays to form polonium. All the commercially produced polonium in the world is made in Russia. WebPolonium werd in juli 1898 ontdekt door Marie Curie en Pierre Curie, toen het werd gewonnen uit het uraniumerts pekblende en werd geïdentificeerd (ontdekt) door zijn sterke radioactiviteit: het was het eerste element dat op deze manier werd ontdekt. Polonium is vernoemd naar het thuisland van Marie Curie, Polen. flying swings daycare
