Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure.The chemical symbol for Iodine is I. Electron Configuration and Oxidation States of Iodine. Electronic configuration. An iodine solution is produced, but is dilute and must be concentrated. The I2 molecules tend to interact via the weak van der Waals forces called the London dispersion forces, and this interaction is responsible for the higher melting point compared to more compact halogens, which are also diatomic. This application is often in conjunction with advanced X-ray techniques such as angiography and CT scanning. [4][91] The Tolerable Upper Intake Level (UL) for adults is 1,100 μg/day. Atomic Volume: 25.74cm 3 / mol. [85], The organoiodine compound erythrosine is an important food coloring agent. Iodine -127. Yes. Possible oxidation states are +1,5,7/-1. The iodine test for starch is still used to detect counterfeit banknotes printed on starch-containing paper. The efficiency is high and energy dispersive spectroscopy is possible, but the resolution is rather poor. Electron Configuration Chart for All Elements in the Periodic Table. electron configuration of iodine? atomic number 53 atomic weight 126.9044 melting point 113.5 °C (236 °F) boiling point 184 °C (363 °F) specific gravity 4.93 at 20 °C (68 °F) oxidation states −1, +1, +3, +5, +7 electron Such an arrangement helps explain the periodicity and periodic trends observed across the elements of the periodic table. Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure. [62], The spectra of the iodine molecule, I2, consists of (not exclusively) tens of thousands of sharp spectral lines in the wavelength range 500–700 nm.

Iodine was discovered by Bernard Courtois in 1811 in France. The major form of thyroid hormone in the blood is thyroxine (T4), which has a longer half-life than T3. You are never expected to go past Calcium when writing the electron configuration of elements. In many cases it will therefore act as an electron acceptor in a Lewis acid-base sense as opposed to a redox sense. Applications of tincture of iodine or Betadine can cause rashes, sometimes severe. Direct contact with skin can cause damage, and solid iodine crystals should be handled with care. Once you have clicked on it, click on "electron configuration" and you'll see the rbital filling diagram of iodine! [4][93][94][75], Natural sources of dietary iodine include seafood, such as fish, seaweeds (such as kelp) and shellfish, dairy products and eggs so long as the animals received enough iodine, and plants grown on iodine-rich soil. The addition of iodine to table salt has largely eliminated this problem in wealthier nations, but iodine deficiency remains a serious public health problem in the developing world today. [90] The toxicity derives from its oxidizing properties, through which it denaturates proteins (including enzymes). [104] Iodine deficiency is the leading cause of preventable intellectual disability, a result that occurs primarily when babies or small children are rendered hypothyroidic by a lack of the element. The condition seems to occur mainly in people over forty, and the risk appears higher when iodine deficiency is severe and the initial rise in iodine intake is high. [92] The general US population has adequate iodine nutrition,[98][99] with women of childbearing age and pregnant women having a possible mild risk of deficiency. The National Institute for Occupational Safety and Health (NIOSH) has set a Recommended exposure limit (REL) of 0.1 ppm (1 mg/m3) during an 8-hour workday. These are further processed by decarboxylation and deiodination to produce iodothyronamine (T1a) and thyronamine (T0a'). Solutions with high elemental iodine concentration, such as tincture of iodine and Lugol's solution, are capable of causing tissue damage if used in prolonged cleaning or antisepsis; similarly, liquid Povidone-iodine (Betadine) trapped against the skin resulted in chemical burns in some reported cases. It penetrates into microorganisms and attacks particular amino acids (such as cysteine and methionine), nucleotides, and fatty acids, ultimately resulting in cell death. [95][96] Iodised salt is fortified with iodine in the form of sodium iodide. Titanium, zirconium, hafnium, and thorium are purified by the van Arkel process, which involves the reversible formation of the tetraiodides of these elements. Under this condition today it is well known that the correct electron configuration should be given by this image of Iodine including the following electron configuration: 1s 2.2s 2.2p x 2.2p y 2.2p z 2.3s 2.3p x 2.3p y 2.3p z 2.3d 10. [73], The iodine value is the mass of iodine in grams that is consumed by 100 grams of a chemical substance typically fats or oils. Possible oxidation states are +1,5,7/-1. Electron configuration of Iodine is [Kr] 4d10 5s2 5p5. Search for "Gelson Luz" in your favorite browser to learn more. [109] Iodine supplementation in selenium-deficient populations is, in theory, problematic, partly for this reason. The electron affinity of iodine is 295.2 kJ mol‑1. Courtois was trying to extract potassium chloride from seaweed. Another significant use is a catalyst for the production of acetic acid by the Monsanto and Cativa processes. Orbital Filling Diagram. [68] These are the minerals that occur as trace impurities in the caliche, found in Chile, whose main product is sodium nitrate. If you don’t have a chart, you can still find the electron configuration. However, new studies suggest that Japan's consumption is closer to 1,000–3,000 μg/day. A step-by-step description of how to write the electron configuration for Iodine (I). In humans, the ratio of T4 to T3 released into the blood is between 14:1 and 20:1. Iodine normally exists as a diatomic molecule with an I-I bond length of 270 pm, one of the longest single bonds known. If you don’t have a chart, you can still find the electron configuration. [85], Inorganic iodides find specialised uses. You will learn at A-Level there are s,p,d and f orbitals, s containing 2 electrons, p containing 6, d containing 10, and f containing 14. Need an editable periodic table to edit? Electron configuration: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 10 5s 2 5p 5. iodide ion has the noble gas configuration of xenon. [69][71], These sources ensure that Chile and Japan are the largest producers of iodine today. In total, they can contain at least 0.02% and at most 1% iodine by mass. Patients with various food allergies (shellfish, egg, milk, etc.) Bromine is the third halogen, being a nonmetal in group 17 of the periodic table. At present, all water-soluble radiocontrast agents rely on iodine. Cesium iodide and thallium-doped sodium iodide are used in crystal scintillators for the detection of gamma rays. This, rather surprisingly, produced a purple vapor, which condensed into dark crystals. Maybe add your school logo, work team or anything else to maker your paper look cool? … 4s 2. Perfluoroalkyl iodides are precursors to important surfactants, such as perfluorooctanesulfonic acid.[85]. Electron Configuration The atomic number of iodine is 53 which shows that there are 53 protons and electrons in an iodine atom. For this example, we will use the iodine atom. Ingestion of this large dose of non-radioactive iodine minimises the uptake of radioactive iodine by the thyroid gland.[83]. [111], People can be exposed to iodine in the workplace by inhalation, ingestion, skin contact, and eye contact. T4 is converted to the active T3 (three to four times more potent than T4) within cells by deiodinases (5'-iodinase). The electron configuration for iodine is like what noble gas? (The typical daily dose of iodine for normal health is of order 100 micrograms; see "Dietary Intake" below.) [112], Some people develop a hypersensitivity to products and foods containing iodine. Nevertheless, check the complete configuration and other interesting facts about Iodine that most people don't know. Hypersensitivity reactions to products and foods containing iodine are apparently related to their other molecular components;[115] thus, a person who has demonstrated an allergy to one food or product containing iodine may not have an allergic reaction to another. Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom. [105] Iodine deficiency is also a problem in certain areas of Europe. For this reason, people at risk of exposure to environmental radioactive iodine (iodine-131) in fallout may be instructed to take non-radioactive potassium iodide tablets. A step-by-step description of how to write the electron configuration for Iodine (I). Electronic configuration of iodide (an not iodine) is similar to that of xenon (the noble gas). Electron Configuration: 1s 2 2s 2 p 6 3s 2 p 6 d 10 4s 2 p 6 d 10 5s 2 p 5. These were the first crystals of iodine ever made. Full electron configuration of iodine: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 10 5s 2 5p 5. tellurium ← iodine → xenon Iodine -127 To see the orbital filling diagram, click on the "Orbital Filling Diagram" button and click on element "53": iodine. Fifteen to 20 mg of iodine is concentrated in thyroid tissue and hormones, but 70% of all iodine in the body is found in other tissues, including mammary glands, eyes, gastric mucosa, fetal thymus, cerebro-spinal fluid and choroid plexus, arterial walls, the cervix, and salivary glands. Atomic Radius: 1.32 Å. ; Siemens, W.D. This unsaturation is in the form of double bonds, which react with iodine compounds. [110], Elemental iodine is also a skin irritant. After filtering and purification the iodine is packed. 4p 6.4d 10. The Japanese Minami Kanto gas field east of Tokyo and the American Anadarko Basin gas field in northwest Oklahoma are the two largest such sources. Iodine probably attacks surface proteins of enveloped viruses, and it may also destabilise membrane fatty acids by reacting with unsaturated carbon bonds. If you count up all of these electrons, you will see that it adds up to 53 electrons. The M shell contains 3s, 3p, and 3d, and solid iodine should.
