For other uses, see Iodine (disambiguation). Chemical element with atomic number 53 (I) Iodine, 53 I Iodine Pronunciation / ˈ aɪ ə d aɪ n, - d ɪ n, - d iː n / (EYE -ə-dyne, -din, -deen ...
lustrous metallic gray solid, black/violet liquid, violet gas: Standard atomic weight A r °(I) ... Spectral lines of iodine: Other properties; Natural occurrence:
The role of iodine in mammary tissue is related to fetal and neonatal development, but its role in the other tissues is not well known. [8] It has been shown to act as an antioxidant [8] and antiproliferant [9] in various tissues that can uptake iodine. Molecular iodine (I 2) has been shown to have a suppressive effect on benign and cancerous ...
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na +) and iodide anions (I −) in a crystal lattice. It is used mainly as a nutritional supplement and in organic chemistry.
Marine natural products are rich sources of organoiodine compounds, like the recently discovered plakohypaphorines from the sponge Plakortis simplex. The sum of iodomethane produced by the marine environment, microbial activity in rice paddies , and the burning of biological material is estimated to be 214 kilotonnes per year. [ 12 ]
Calcium iodate, Ca(IO 3) 2, is the principal ore of iodine. It is also used as a nutritional supplement for cattle. It is also used as a nutritional supplement for cattle. Potassium iodate , KIO 3 , like potassium iodide , has been issued as a prophylaxis against radioiodine absorption in some countries.
The iodine cycle is a biogeochemical cycle that primarily consists of natural [1] and biological processes [3] that exchange iodine through the lithosphere, hydrosphere, and atmosphere. [ 3 ] [ 2 ] Iodine exists in many forms, but in the environment, it generally has an oxidation state of -1, 0, or +5.
Iodine-135 is an isotope of iodine with a half-life of 6.6 hours. It is an important isotope from the viewpoint of nuclear reactor physics . It is produced in relatively large amounts as a fission product , and decays to xenon-135 , which is a nuclear poison with the largest known thermal neutron cross section , which is a cause of multiple ...
