polonium atomic number

Because of its short life isotopes it is found very rarely in nature. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Twenty five isotopes of polonium are known, with atomic masses ranging from 194 to 218. Polonium is a radioactive chemical element (atomic number 84) that was discovered in 1898 by Marie Curie, who named the element after her country, Poland. The element has 33 radioactive isotopes, including polonium-208 and polonium-210. This technology is ancient by modern standards, but the properties are still useful for certain applications. There are around 50 synthetic or artificially made compounds of polonium. Hence Polonium was extracted from the uranium ore and identified solely by its strong radioactivity. Its atomic number 84 and its symbol is Po. The atomic number of polonium is 84 and atomic mass is 209. Isotopes of mass 209 (half-life 103 years) and mass 208 (half-life 2.9 years) can be prepared by alpha, proton, or deuteron bombardment of lead or bismuth in a cyclotron, but these are expensive to produce. Twenty five isotopes of polonium are known, with atomic masses ranging from 194 to 218. It is a scarce element that is produced in nuclear reactors. Polonium-210 is the most readily available. Melting point 527K. There are very few naturally occurring compounds of polonium. — In-game description Polonium (atomic number 84, symbol Po) is a radioactive element and a very rare semi-metal. Polonium, Po, atomic number 84. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Chemical Characteristics. Polonium is an intense source of alpha particles and in sufficient quantities will generate enough heat for radioisotope thermoelectric generators. Polonium (Po) is a silvery-gray metal that has the atomic number 84 in the periodic table in Group 16. Isotopes of mass 209 (half-life 103 years) and mass 208 (half-life 2.9 years) can be prepared by alpha, proton, or deuteron bombardment of lead or bismuth in a cyclotron, but these are expensive to produce. Polonium was discovered by Marie Curie and her husband Pierre Curie in 1898. Polonium-210 is the most readily available. The first element to be discovered by radiochemical analysis, polonium was discovered in 1898 by Pierre and Marie Curie, who were investigating the radioactivity of a certain pitchblende. Polonium, a radioactive, silvery-gray or black metallic element of the oxygen group (Group 16 [VIa] in the periodic table). Polonium-211 atom is the radioactive isotope of polonium with relative atomic mass 210.986637 and half-life of 0.516 s.
