Reactivity of polonium
WebIt reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several of the nonmetallic elements. Several million tons of sulfur are produced each year, mostly for the manufacture of sulfuric acid, which is widely used in industry. WebPolonium is an alpha-emitter, hence it is used in antistatic devices and for research purposes. It is used in the form of a thin film on a stainless steel disc as an alpha-particle source. It is used to eliminate static electricity …

The first element to … WebCharacteristics: 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. 1 gram of Po emits as many alpha particles as 5 kilograms of radium.
