Everything about Number 53 – iodine

Iodine é an element of qu í mico ú number 53 at ô mico situated in ê domains halog Group (Group 17) peri ó tip table of the elements. Your s í mbolo é (i) (from Greek violet). This element can be found in the form á River as the diatomic molecular iodine.
É an element of tra ç and é used mostly in medicine, photography, and as a dye. Chemically, iodine é less reactive and halog ê nio electronegativo. As with all remaining halog ê domains (members of Group VII in peri ó tip), iodine (d) á mol é plates form diatomic and é consequences ü often iodine from molecular formula I2 ó.
As the entire halog ê domains form a large n á ú mere compounds with other elements, but é less reactive group and has certain character í á metabolic characteristics met. You can submit v ê á rivers States oxidizes ç ã:-1, 1, 3, 5, 7.
also reactive with merc É ú River and enx ô fre. Iodine é the halog ê nio less abundant, running in the crust with a concentrated ç ã of 0.
14 ppm, when sea water in á your â download for 0,052 abund ppm. Iodine é obtained from iodides, i present the á sea water and seaweed, or in the form of nitrates of iodate IO3-from the saltpetre (previously these).
The first m é all ã for the ç separating the iodine of Chilean nitrate was discovered by don Pedro Gamboni, in your Office ó River of nitrate of Sevastopol, located on the Tarapac regi ã.
H á 37 ó iodine is tops, but only the I-127 á vel é est. The is ó top artificial radioactive I-131 (a beta emitter) with a half-life of 8 days was used in the treatment of cancer and other pathologies of the gl â ndulé of tir ó ide. Iodine-129 (with a half-life of approximately 16 million ã the years) can be produced of Xenon-129 in the atmosphere, land, or also with the decay of uranium ç ã-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.
