What is an unusual fact about iodine?
Interesting Iodine Facts: Iodine is the 47th most abundant element in the solar system. It is the 60th most common element in the Earth’s crust. Iodine is very soluble in water and is found more abundantly in the ocean and in brine at 0.04 parts per million. It is a blue-black solid.
What is special about the iodine?
Iodine is the least reactive of the halogens as well as the most electropositive, meaning it tends to lose electrons and form positive ions during chemical reactions. It is also the heaviest and the least abundant of the stable halogens.
What are 3 uses for iodine?
Today, iodine has many commercial uses. Iodide salts are used in pharmaceuticals and disinfectants, printing inks and dyes, catalysts, animal feed supplements and photographic chemicals. Iodine is also used to make polarising filters for LCD displays.
Why is it named iodine?
Iodine gets its name from the Greek word “iodes” which means “violet.” Iodine has one stable isotope that occurs naturally, iodine-127. Many people get the iodine they need in their diets from eating seaweed.
Is there iodine in eggs?
On average, one large egg contains 24 mcg of iodine, or 16\% of the daily value ( 6 , 24). Summary The majority of iodine in eggs is found in the yolk. On average, one large egg provides 16\% of the daily recommended amount.
Who invented iodine?
Bernard Courtois
Iodine/Discoverers
Iodine was first discovered by Barnard Courtois, a French chemist in 1811 while extracting potassium and sodium from seaweed ash. When he accidentally added sulfuric acid, a violet colored cloud evolved from the mass.

Who discovered iodine?
The discovery of iodine was made incidentally during the early part of the 19th century. In 1811, while extracting sodium salts necessary for the manufacture of gunpowder, Bernard Courtois, a French chemist, observed an unusual purple vapor arising from seaweed ash treated with sulphuric acid [1].

What elements are in iodine?
Iodine is classified as a halogen — a subset of very chemically reactive elements (Group 17 on the periodic table) that exist in the environment as compounds rather than as pure elements. The other halogens include fluorine (F), chlorine (Cl), bromine (Br) and astatine (At).
