Iodine
1) Latin: Iodum, Czech: Jod, Croatian: Jod. The word Iodine came from the Greek word meaning "iodes", or "meaning violet or purple". (wikipedia.com) 2) "iodine is a bluish-black, lustrous solid."(wikapedia.com)
3) I-127
| Isotope | Atomic mass (ma/u) | Natural abundance (atom %) | Nuclear spin (I) | Magnetic moment (μ/μN) |
|---|---|---|---|---|
| 127I | 126.904473 (5) | 100 | 5/2 | 2.81328 |
4) Iodine has 53 electrons and 5 shells of electrons.
5) The atomic mass of iodine is 140 x 10-12
6) It's density is 4940 kg m-3, its melting point is at 386 degrees Fahrenheit and its boiling point is at 457 degrees Fahrenheit
7) Their is 200 ppb of iodine in our bodies, 490 ppb in Earth's crust, and 1 ppb in the universe.
8)iodine chloride ICl- has a ruby red color, and is a crystalline solid.
Iodine Fluoride IF- an unstable solid at -45 degrees Celsius
9) Iodine was discovered by Bernard Courtois in 1800
10) Iodine is used in mostly in the medical field:
-The stable iodine isotope is used for maintaining good health. A deficiency of Iodine causes Hypothyroidism.
-The radioactive Iodine isotope is used in radioactive Iodine therapy.
11) Extreme iodine deficiency can cause mental retardation. Found in some seafood."Iodine and its compounds are primarily used in nutrition, the production of acetic acid and polymers. Iodine's relatively high atomic number, low toxicity, and ease of attachment to organic compounds has made it a part of many X-ray contrast materials in modern medicine." (Wikipedia.com)
