पोलोनियम
Also known as Po, element 84, 84Po
Polonium is a chemical element; it has symbol Po and atomic number 84. A rare and highly radioactive metal (although sometimes classified as a metalloid) with no stable isotopes, polonium is a chalcogen and chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbours in the periodic table: thallium, lead, and bismuth. Due to the short half-life of all its isotopes, its natural occurrence is limited to tiny traces of the fleeting polonium-210 (with a half-life of 138 days) in uranium ores, as it is the penultimate daughter of natural ur
AI overview
Polonium is a rare, highly radioactive chemical element (symbol Po, atomic number 84) with no stable forms, making it chemically similar to selenium and tellurium but with some metallic properties. Because all of its isotopes decay quickly, polonium is found only in tiny traces in nature, primarily as polonium-210 in uranium ores where it forms as part of uranium's decay process.
