Description
Diagram of the nuclear composition and electron configuration of an atom of polonium-209 (atomic number: 84), an isotope of this element. The nucleus consists of 84 protons (blue) and 125 neutrons (yellow). 84 electrons (white) bind to the nucleus, successively occupying available electron shells (rings). Polonium is a radioactive metalloid in group 16, period 6, and the p-block of the periodic table. Discovered in 1898 by the Curies, it was named after Poland. Polonium-210, which forms in uranium ores, has a half-life of 138 days, emitting an alpha particle from its unstable nucleus to form lead-206
