![]() They have created a complete suite of short videos on every element on the periodic table of elements. The video below is from the University of Nottingham's periodic videos project. Sodium has one isotope found in nature: Symbol Sodium is a plentiful, relatively cheap metal that causes minimal corrosion on the reactor equipment and is easily purified. Sodium makes an ideal coolant for a fast reactors because the liquid can operate at high temperatures without high pressure. Jacob Berzelius preferred the shorter natrium, from which we get the chemical symbol for sodium, Na. Gilbert suggested the new element should be called natronium. (2),(3) In Germany caustic soda was known as natronlauge and L. The metal is sometimes used to remove heat from nuclear reactors, particularly sodium-cooled fast breeder reactors. He named the new metal sodium, because he had used caustic soda or, more simply, soda, as his source of the element. Sodium compounds are often used as part of various reagents in chemistry. Sodium chloride (NaCl) the most common form of salt, including the salt that is added to food, for de-icing, and as salt blocks for animals.

Solubilities of inorganic and organic compounds c. Water accelerates the oxidation process, and iodide can also produce I 2 by photooxidation, therefore for maximum stability sodium iodide should be stored under dark, low temperature, low humidity conditions. I 2 and I − complex to form the triiodide complex, which has a yellow color, unlike the white color of sodium iodide. ![]() Iodides (including sodium iodide) are detectably oxidized by atmospheric oxygen (O 2) to molecular iodine (I 2). Solubility of NaI (g NaI/kg of solvent at 25 ☌) Sodium iodide exhibits high solubility in some organic solvents, unlike sodium chloride or even bromide: After experiments on rabbits and dogs he settled upon sodium iodide as the best medium. Radiocontrast Īntónio Egas Moniz searched for a radiocontrast agent for cerebral angiography. The wavelength of maximum emission is 415 nm. Sodium iodide can be used both as single crystals and as polycrystals for this purpose. Crystals with a higher level of doping are used in X-ray detectors with high spectrometric quality. Fine-tuning of some parameters (i.e., radiation hardness, afterglow, transparency) can be achieved by varying the conditions of the crystal growth. The crystals are usually coupled with a photomultiplier tube, in a hermetically sealed assembly, as sodium iodide is hygroscopic. NaI(Tl) is the most widely used scintillation material. Sodium iodide activated with thallium, NaI(Tl), when subjected to ionizing radiation, emits photons (i.e., scintillate) and is used in scintillation detectors, traditionally in nuclear medicine, geophysics, nuclear physics, and environmental measurements. Some radioactive iodide salts of sodium, including Na 125I and Na 131I, have radiopharmaceutical uses for thyroid cancer and hyperthyroidism or as radioactive tracer in imaging (see Isotopes of iodine > Radioiodines I-123, I-124, I-125, and I-131 in medicine and biology). This method, the Finkelstein reaction, relies on the insolubility of sodium chloride in acetone to drive the reaction: R–Cl + NaI → R–I + NaCl Nuclear medicine Sodium iodide is used for conversion of alkyl chlorides into alkyl iodides. ![]() Monatomic NaI chains grown inside double-wall carbon nanotubes.
