The same characteristics, however, make TTX a very valuable research tool for studying neural networks that form the basis of the workings of the brain, of which we are just now beginning to gain an understanding. Chemists have also recently gained a surprising insight into the nature of sodium itself.
Yanming Ma and co-workers demonstrated 4 that compression dramatically changes the optical properties of the metal. Exposing sodium to increasing pressure causes a successive loss of visible light reflection, turning it into a transparent material at about GPa. This transition is ascribed to a hybridization between p and d electrons, repelled by core electrons to occupy the interstices within the sodium lattice. From fireworks and nuclear reactors to the human brain and structural insights, sodium is undoubtedly part of an exciting history of scientific discovery, with no end in sight just yet.
This essay was selected as a winning entry in our writing competition, see this month's Editorial on p for more details.
Gmelin, L. Handbuch der anorganischen Chemie 2 Heidelberg, Google Scholar. Kirchhoff, G. Annalen der Physik und Chemie , — Article Google Scholar. Daniel, J. Ma, Y. Nature , — Since sodium can ignite on contact with water, it must be stored in a moisture free environment. Sodium is used in the production of titanium , sodamide, sodium cyanide, sodium peroxide, and sodium hydride. Liquid sodium has been used as a coolant for nuclear reactors.
Sodium vapor is used in streetlights and produces a brilliant yellow light. Other uses are: to improve the structure of certain alloys; in soap, in combination with fatty acids, in sodium vapor lamps, to descal metals, to purify molten metals. Solid sodium carbonate is needed to make glass. Sodium is, after chloride, the second most abundant element dissolved in seawater.
The most important sodium salts found in nature are sodium chloride halite or rock salt , sodium carbonate trona or soda , sodium borate borax , sodium nitrate and sodium sulfate. Sodium salts are found in seawater 1. The production of salt is around million tonnes per year; this huge amount is mainly extracted from salt deposits by pumping water down bore holes to dissolve it and pumping up brine. The sun and many other stars shine with visible light in which the yellow component dominates and this is given out by sodium atoms in a high-energy state.
Sodium is a compound of many foodstuffs, for instance of common salt. It is necessary for humans to maintain the balance of the physical fluids system. Sodium is also required for nerve and muscle functioning. Too much sodium can damage our kidneys and increases the chances of high blood pressure.
