 * <span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;">How, when and who discovered Iodine **<span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;"> – It was discovered by a French chemist Barnard Courtois in 1811. Barnard was extracting Sodium and Potassium compunds from seaweed ash, after that he removed the compounds, the added a little to much sulfuric acid and then it became Iodine.
 * <span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Cost of Iodine - **<span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;">$8.30per 100 grams.
 * Unusual Facts ****<span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;"> – **<span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;">1.) Iodine is used to disinfect cow teats after the cow has been milked! 2.) Silver iodide is used in photography. 3.)The name for iodine comes from the Greek word iodes, which means violet. Iodine gas is violet-colored.
 * <span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Orbital Notation – **<span style="font-family: 'Baskerville Old Face','serif'; font-size: 24px;">1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p5 <span style="color: black; font-family: 'baskerville old face','serif'; font-size: 24px;">.
 * <span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Valence Electrons - **<span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;">There are 7 valence electrons in Iodine.
 * <span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Chemical and Physical Properties – phyisical: **<span style="font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Iodine is a solid diatomic non-metal that is very pungent in odor and a corrosive poison. The density of iodine is 4.94 g/mL, which makes it sink in water. **Chemical:** Iodine is not reactive with Oxygen or Nitrogen. Iodine reacts with Hypoiodite.
 * <span style="font-family: 'Baskerville Old Face','serif'; font-size: 24px;">2 Chemical Reactions -1.) **<span style="color: black; font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Iodine, I2, reacts with bromine, Br2, form the very unstable, low melting solid, interhalogen species iodine(I) bromide. **2.)** <span style="font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Iodine reacts with hot concentrated nitric acid to form iodic acid. The iodic acid crystallizes out on cooling.
 * <span style="font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Mined, Produced – **<span style="font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Iodine is commonly found in the Great Lakes, Appalachian, and Northwestern United States regions and in most of Canada. Iodine is produced in 9 countries, Such as Chile, Japan and the United States.
 * <span style="font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Commercial and Industry use – **<span style="font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Iodine is used in a lot of foods, such as seafood’s. Also Iodine is used in the medical field, with CAT scans, X-rays as well as CT scans.
 * <span style="font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Minerals- **<span style="font-family: 'Baskerville Old Face','serif'; font-size: 24px;">Iodine helps make thyroid hormones. Also Iodine is found in seawater, rocks and some types of soil. And in the United Kingdom Iodine is found in cows’ milk, depending on what the cows have been feed.
