Polonium symbol

Its extreme toxicity is attributed to intense radioactivity, capable Polonium (atomic number 84, symbol Po) is a radioactive element and a very rare semi-metal. The element has 33 radioactive isotopes, including polonium-208 and polonium-210. It is a scarce element that is produced in nuclear reactors. Neurons are used to bombard bismuth-209, and bismuth-210 is formed as a result. Download 212 Polonium Symbol Stock Illustrations, Vectors & Clipart for FREE or amazingly low rates!

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, a uranium ore. A radioactive element that is a member of the chalcogen family. It has the atomic symbol Po, atomic number 84, and the atomic weight of the isotope with the longest half-life (209Po) is 208.98. Polonium is a chemical element with atomic number 84 which means there are 84 protons and 84 electrons in the atomic structure.
