Chemical Elements

Periodic Table

Definition of the Polonium Element
A radioactive metallic element that is similar chemically to tellurium and bismuth, occurs especially in pitchblende and radium-lead residues, and emits an alpha particle to form an isotope of lead. Also called Radium F.

Origin / Meaning of the name Polonium
The name originates from Poland the home of Marie Curie. Madame Curie was born Maria Sklodowski in Warsaw, Poland in 1867.

Classification of the Polonium Element
Polonium is classified as a "Metalloid" element and is located in Groups 13, 14,15, 16 and 17 of the Periodic Table. An element classified as a Metalloid has properties of both metals and non-metals. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers.

Facts about the Discovery and History of the Polonium Element
Polonium was discovered by Marie Curie and Pierre Curie in 1898

Occurrence the Polonium Element
A very rare element in nature
Obtained from pitchblende, decay of radium

Associated Uses of Polonium
Thermoelectric power in space satellites
To eliminate static charges
Removes dust from photographic films

Polonium and the Periodic Table
Check out Polonium on the Periodic Table which arranges each chemical element according to its atomic number, as based on the periodic law, so that chemical elements with similar properties are in the same column. Our Periodic Table is simple to use - just click on the symbol for Polonium for additional information and for an instant comparison of the Atomic Weight, Melting Point, Boiling Point and Mass - G/cc with any other element. An invaluable source of facts and information as a Chemistry reference guide.

Polonium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day but still all fitting into his concept of  the "Periodic Table" in which Polonium is just one element that can be found.
