poloniumn.

Brit.

/pəˈləʊnɪəm/, U.S.

/pəˈloʊniəm/

Origin: A borrowing from French. Etymon: French polonium.

Etymology: < French polonium < (M. Curie and P. Curie 1898, in Comptes rendus de l'Acad. des Sci. 127 177) < post-classical Latin Polonia Poland (see polony adj. and n.²) + French -ium -ium suffix, with reference to the country of birth of Marie Curie, the co-discoverer.

Chemistry.

A rare, highly radioactive, metallic chemical element, atomic number 84, present in some uranium ores, the longest-lived isotope (polonium-209) having a half-life of around 103 years, and another isotope (polonium-210) being used to eliminate static electricity in certain industrial processes, to remove dust from photographic films, and as a source of alpha particles. Symbol Po.Polonium was discovered in pitchblende by Marie and Pierre Curie in 1898.

1898 W. Crookes Addr. Brit. Assoc. 26 A new constituent of the uranium mineral pitchblende... The radiant activity of the new body, to which the discoverers have given the name of Polonium, needs neither the excitation of light nor the stimulus of electricity.

1922 T. M. Lowry Inorg. Chem. xlv. 905 Polonium was discovered by M. and Mme. Curie in pitchblende... The name was given in honour of the country in which Mme. Curie was born.
