| My Nucleus My nucleus has 53 protons There is only one naturally occuring isotope Iodine-127. I also have 15 other radiosotope. My half-lives range from 3.6 mi. to 17 million years. My average atomic mass is 126.90 grams/mole.  | My Electrons I have 53 electrons when I am neutral. My electrom configuration is: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p5 or [Kr].4d10.5s2.5p5  My shell structure is: 2.8.18.18.7 | My Properties The color of iodine is dark violet or a bluish black color and non-metalic. It is a non-metal so it doesn't conduct electricity or heat. It is a solid at room temperature.My boiling point is 365.7 degrees F. My melting point is 236.3 degrees F.  |
| My Home (Body, Planet, Universe) The geological information of iodine. Iodine is found in the human body, the universe and even in sea water. But iodine is never found as a free element in nature. Iodine also comes from seaweed like from Irish moss.  | Iodine  | My Compounds (My Friends!) Iodine has componds with fluorine, chlorine, bromine, and oxygen. It has 4 compounds with flourine, 2 with chlorine, 1 with bromine, and 3 with oxygen. I also have a compound with nitrogen called nitrogen triiodide.  |
| My Story Iodine was discoverd in 1811in France by Bernard Courtois. Iodine is of Greek Origin "iodes" meaning "violet". Iodine was discvered in seaweed.  | My Jobs I am used in medicine(disinfectant for eternal wounds), in photography, and as a nutrient added to salt. Iodine treats tumors in the thyroid gland.  |  |
