Facts about the
Definition of the Element Polonium
The Element Polonium is defined as...
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.
Interesting Facts
about the Origin and Meaning of the element name Polonium
What are the origins of the word Polonium ?
The name originates from Poland the home of Marie Curie. Madame
Curie was born Maria Sklodowski in Warsaw, Poland in 1867.
Facts about the
Classification of the Element Polonium
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 and Info about
the element Argon - 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
which includes the Polonium element. The famous Russian Scientist,
Dimitri Mendeleev, perceived the correct classification method of
"the periodic table" for the 65 elements which were known in his
time. Polonium was discovered by Marie Curie and Pierre Curie in
1898. The Standardised Periodic Table 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.
