Background info: Polonium was discovered in 1898. It was discovered by Piere and Marie Curie. They discovered it while seeking the cause of radioactivity. It's atomic number is 84 and it is named after Poland	Anchors: Background Info Energy levels Isotopes Slogan Uses History Glossary Bibliography Structure Reactions Facts	Uses: Mixed or alloyed with beryllium to provide a source of neutrons. Used for eliminating static charges, in textile mills (B-sources are more common and less dangerous. Used on brushes for removing dust from photographic films. Thermoelectric power in space satellites. Source of neutrons
History: Polonium also called Radium F was the first element discovered by Piere and Marie Curie. They were seeking the cause of radioactivity of pitchblende from Joachimsthal, Bohemia. The electroscope showed it seperating the bisthum.

Reactions: Dissolved steadily in dilute acids, but only slightly in soluble alkalis. Can be dangerous if it is not handled carefully, because it gives up electrons because its valence electrons.	Structure: Standard State: Solid at 298 K Color: Silvery When solid the crystal structure of polonium is cubic.	Bibliography: Holt, Rinehart, and Winston. Physical Science.
