Everything about Atomic 53 – IodineIodine is a chemical element in the Atomnr. 53, which is the periodic table of the elements in the Group of halogens (Group 17). Its symbol is (i) (from the Greek violet). This element can be found in the molecular form as iodine zweiatomig. It is a trace element and is used mostly in medicine, photography and colour. Chemically, iodine is the few responsive and electro-negative halogen. As with all other halogens (members of the Group VII in the periodic table), iodine forms diatomic molecules and therefore is the molecular formula i2 iodine. Like halogens all form many funds with other elements, but the Group of the responding a few and has certain metallic properties. You can submit various oxidation States: - 1, 1, 3, 5, 7. It is reacting with mercury and sulfur. Iodine is the halogen is less abundant and performs in the crust with a concentration of 0. 14 Ppm, while in the sea water, his exuberance is 0.078 ppm. IO3-from nitrates of saltpeter get (previously separated from them) of the Iodides, i present in sea water and in the seaweed, or in the form of Jodaten iodine,. The first method for the separation of iodine of nitrates was Pedro Gamboni attract by the Chileans, in her Office discovered Sevastopol nitrate works, located in the region of Tarapac. There are 37 isotopes of iodine, but only the I-127 is resistant. The radioisotope artificial I-131 (a beta emitter) with a half-life of 8 days been used in the treatment of cancer and other pathologies of the thyroid gland.Iodine-129 (with a half-life of approximately 16 million years) can be produced from the Xenon-129 in the Earth atmosphere or by the decay of uranium-238. While the uranium-238 is produced for some activities related to nuclear energy, his presence (the ratio 129I\/I) can view the type of employment in a particular place. For this reason the 129i in the studies of rain water into the port was used on the Chernobyl accident. It has also been used as an indicator in the surface water, and as an indicator of the dispersal of the waste in the environment. Other applications can be locked by the production of iodine-129 in the Lithoshäre by some mechanisms of corruption. In many ways the 129i is similar to the chlorine-36. It is a soluble halogen, relatively unresponsive, exists mainly as a solvated anion not and is in situreaktionen and cosmog produced by thermonuclear. In the hydrological studies, 129i concentrations generally occur as the ratio of 129i to the total iodine on (practically all iodine-127). As in the case of ratio 6 CL \/ CL, 129I\/I in the natural relations, 10 - are quite small 14-10 (thermonuclear Hoechst129I\/I during the 1960s and 1970s of the obtained values of 10-7). The 129i differs from the chlorine-36 that its half-life is greater (16 compared to 0). 3 Million years), it is highly Biophilic and found in multiple Ionic forms (usually I - and iodates) which have different chemical behavior. Administration recommends 150 micrograms of iodine per day for men and women food and State drugs (FDA). This is necessary for the production of thyroid hormones. Natural sources of iodine include sea products such as algae and some fish, as well as the plants that are grown in iodine rich soil. One of the iodine rich algae is the Brown seaweed, sea baß, cod, Pollock and sea Rod are in this mineral rich. Salt for daily consumption is often reinforced with iodine and known as iodized salt. It may be due to an immune disorder that this leads to an excessive production of thyroid hormones, which allow not physiological working of the thyroid gland, or also by an excessive intake of iodine by foods such as algae or supplements, which are used to promote weight loss, that are high in the iodine. Symptoms include: increase the basal metabolic rate, insatiable appetite, thirst, weight loss, general weakness, intolerance to heat, nervousness, heart problems, including. The iodine is corrosive, care is required when it dealt with iodine, because direct contact with skin can cause injury. Iodine steam is very irritating to the eyes. Minimal contact give a dose of eye drops to the eye \/ s. It is dangerous to the mucous membranes. The concentration of iodine in the air should not exceed 1 mg \/ m. If it is mixed with ammonia, can triyoduro of nitrogen form, which is extremely sensitive and able to unexpectedly explode. iodine tablets for radiation, Implant Cost, Slovar angleško slovenski, Kinder rucksack, http://blog.buy4cheap.net | |
