 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.

Polonium dissolves in dilute acids, but it is only slightly soluble in alkalis. It is fairly volatile: about half of a sample of it will evaporate within three days, unless it is kept in a sealed container. Also called Radium F. The Atomic Number of this element is 84 and the Element Symbol is Po.

 

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.

Periodic Table Group and Classification of the of the Polonium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. 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 one of the Metalloids has the properties of both metals and Non-Metals. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the
List of Metals.

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

What is 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 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.
