It is classed as a metal as its electrical conductivity decreases as its temperature rises. Because of this property it is used in industry to eliminate dangerous static electricity in making paper or sheet metal. Photographs and descriptions of many samples of the element Polonium in the Periodic Table. Polonium is a chemical element with the symbol Po and atomic number 84. A rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and bismuth. Polonium - Properties, history, name origin, facts, applications, isotopes, electronic configuation, crystal structure, hazards and more; Interactive periodic table of the chemical elements.

Polonium Data Atomic Number: 84 Atomic Mass: 209 Oxidation States: 4, 2 Polonium är ett grundämne i det periodiska systemet med den kemiska beteckningen Po och har atomnummer 84 med en atommassa på 209 u och den tillhör ämnesklassen Övrig metall. Polonium-210, in particular, is very dangerous, and processing requires strict procedures, precautions, and special equipment. The nuclear facilities where uranium and polonium are processed are strictly regulated and monitored as required by international agreements. In 1898, Marie Curie discovered radium and polonium after refining pitchblende.
