Facts about the Definition of the Element Iodine
The Element Iodine is defined as...
A lustrous, violet-black, corrosive, poisonous halogen element having radioactive isotopes, especially I 131, used as a medical tracer and in thyroid disease diagnosis and therapy. Iodine compounds are used as germicides, antiseptics, and dyes.
Interesting Facts about the Origin and Meaning of the element name Iodine
What are the origins of the word Iodine ?
The name originates from the Greek word Iodes meaning "violet".
Facts about the Classification of the Element Iodine
Iodine is classified as an element in the 'Halogens' section which can be located in group 7 of the Periodic Table. The term "halogen" means "salt-former" and compounds containing halogens are called "salts". The halogens exist, at room temperature, in all three states of matter - Gases such as Fluorine & Chlorine, Solids such as Iodine and Astatine and Liquid as in Bromine.

Facts and Info about the element Iodine - 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 Iodine 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. Iodine was discovered by Charles Bernard Desormes (1777-1862) in 1811. 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 Iodine is just one element that can be found.
