po·lo·ni·um   Pronunciation Key  (p-ln-m)
n. Symbol Po
A naturally radioactive metallic element, occurring in minute quantities as a product of radium disintegration and produced by bombarding bismuth or lead with neutrons. It has 27 isotopes ranging in mass number from 192 to 218, of which Po 210, with a half-life of 138.39 days, is the most readily available. Atomic number 84; melting point 254°C; boiling point 962°C; specific gravity 9.32; valence 2, 4. See table at element.
[From Medieval Latin Polnia, Poland (the native country of Pierre and Marie Curie, the element's discoverers).]

polonium

\Po*lo"ni*um\, n. [NL. So named after Poland, in L. form Polonia, one of the discoverers being a Pole.] (Chem.) A supposed new element, a radioactive substance discovered by M. and MMe. Curie in pitchblende. It is closely related chemically to bismuth. It emits only alpha rays and is perhaps identical with radium F.
