Polonium, kemisk, framförande, potta, element., 3. Polonium
It is in Group 16 (VIA) on the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. The other chalcogen elements are oxygen, sulfur, selenium, and tellurium. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. In the periodic table, the elements are listed in order of increasing atomic number Z. Electron configuration of Polonium is [Hg] 6p4. Possible oxidation states are +2,4. The chemical symbol for Polonium is Po. Polonium is 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.
We start with the inconspicuous and seemingly harmless element occupying the lower right side of the table, Polonium. Polonium is located in Group 16 and period 6 in the periodic table of elements. It's classified as a metal because polonium's electrical conductivity decreases as its temperature rises, according Polonium-210 is a very strong emitter of alpha particles. A single gram of polonium-210 creates 140 Watts of heat energy and is being considered as a lightweight heat source for thermoelectric power for spacecraft. Polonium-210 has a half-life of 138.39 days. Polonium's most stable isotope, polonium-209, has a half-life of 102 years.

Polonium is the chemical element with symbol Po and atomic number 84 in the periodic table. This element was discovered by Marie Sklodowska Curie and Pierre Curie in 1898. Uses of Polonium. Polonium is an alpha-emitter, hence it is used in antistatic devices and for research purposes. Polonium is a relatively noble metal, similar to silver, but very radioactive. The most stable isotope is the synthetically produced 209 Po with a half-life of 103 years. Almost all of the natural occuring Polonium is 210 Po with a half-life of only 138 days.
100g Polonium pro Jahr können durch Bombardierung von Bismuth mit Neutronen in einem Nuklearreaktor produziert werden. Gesundheitliche Auswirkungen von Polonium
