Iodine

Iodine (I)

Iodine is the 53rd element in the periodic table and has a symbol of I and atomic number of 53. It has an atomic weight of 126.90447 and a mass number of 127. Iodine has fifty-three protons and seventy-four neutrons in its nucleus, and fifty-three electrons in five shells. It is located in group seventeen, period five and block p of the periodic table. Dark violet nonmetallic element, belongs to group 17 of the periodic table. Insoluble in water. Required as a trace element for living organisms. One stable isotope, I-127 exists, in addition to fourteen radioactive isotopes. Chemically the least reactive of the halogens, and the most electropositive metallic halogen. Discovered in 1812 by Courtois.

History

Iodine was discovered by French chemist Bernard Courtois in 1811. He treated the liquor obtained from the extraction of kelp, with sulfuric acid to produce a vapour with a violet color. In 1812, Joseph Louis Gay-Lussac demonstrated that iodine was an element and its chemical relationship to chlorine. From the Greek word iodes, violet

DiscoverersBernard Courtois
Discovery LocationFrance
Discovery Year1811
Etymology (Name Origin)Greek: iôeides (violet colored).
PronunciationEYE-eh-dine (English)
Elemental iodine is toxic if taken orally
Kelp was the main source of natural iodine in the 18th and 19th centuries

Uses

Iodine compounds are important in organic chemistry and very useful in medicine. A solution containing potassium iodide and iodine in alcohol is used to disinfect external wounds. Silver iodide is a major ingredient to traditional photographic film. Iodine is added to table salt to prevent thyroid disease. Required in small amounts by humans. Once used as an antiseptic, but no longer due to its poisonous nature.
