What is Polonium? 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 chemical element with atomic number 84 which means there are 84 protons and 84 electrons in the atomic structure. The chemical symbol for Polonium is Po. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. The nucleus is composed of protons and neutrons.

Dessa radioaktiva Han förgiftades av ett synnerligen ovanligt och svårframställt gift som heter Polonium-210. Det är svagt radioaktivt men är ett mycket kraftigt gift. Syftet får antas 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 (Po), a radioactive, silvery-gray or black metallic element of the oxygen group (Group 16 [VIa] in the periodic table). 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.
