[210Po]"}, {"from": "gpt", "value": "The molecule is a chemical element with the symbol Po and atomic number 84, discovered in 1898 by Marie and Pierre Curie. A rare and highly radioactive metalloid, polonium is chemically similar to bismuth and tellurium, and it occurs in uranium ores. When it is mixed or alloyed with beryllium, polonium can be a neutron source and has been used in this capacity as a neutron trigger or initiator for nuclear weapons. Polonium has also been studied for possible use in heating spacecraft. It is unstable and all isotopes of polonium are radioactive. It is one ingredient of cigarette. (L1842)"}]
