Infobox sodium<br/>[[File:Sodium.jpg|thumb|Sodium pellets in a container]]<br/>'''Sodium''' (symbol '''Na''', from the Latin name ''natrium'') is the [[chemical element]] number 11 in the periodic table of elements. It follows that its [[nucleus (physics)|nucleus]] includes 11 [[proton]]s, and 11 [[electron]]s orbit around it (according to the simplified model known as "Niels Bohr atom"). Even if many [[isotope]]s can be artificially made, all decay in a short time. As a result, all sodium found in nature (mainly in [[sea]] water) has the composition <sub>11</sub>Na<sup>23</sup>, meaning that the nucleus includes 12 [[neutron]]s. The [[atomic mass]] of sodium is 22.9898; if it is rounded, it would be 23.<br/><br/>== Properties ==<br/><br/>Sodium is a light, silver-coloured [[metal]]. Sodium is so soft that it can be easily cut with a knife. When it is cut, the surface will become white over time. This is because it reacts with air to form [[sodium hydroxide]] and [[sodium carbonate]]. Sodium is a little lighter than water; when it reacts with water it floats. This reaction is very fast. [[Hydrogen]] and [[sodium hydroxide]] are produced. The hydrogen may [[flame|ignite]]. Since sodium melts at a low temperature, it melts when it reacts with water. It has one [[valence electron]] which is removed easily, making it highly reactive. <br/><br/>Compared with other alkali metals (metals in the first column of the [[periodic table]]), sodium is usually less reactive than [[potassium]] and more reactive than [[lithium]].<ref>title=Reactivity of Alkali Metals</ref><br/><br/>=== Chemical compounds ===<br/>These are [[chemical compound]]s that contain [[sodium]] [[ion]]s.

He made it by the [[electrolysis]] of sodium hydroxide. It is named after soda, a name for sodium hydroxide or [[sodium carbonate]].<br/><br/>== Use as element ==<br/>It is used in the preparation of organic compounds. It is also used in the street lights that are orange, and ultra violet lights.<br/><br/>== Use as compounds ==<br/><br/>Sodium compounds are used in soaps, toothpaste, baking and antiacids.<br/>.<br/><br/>== Occurrence and production ==<br/>Sodium does not exist as an element in nature; its easily removed valence electron is too reactive. It exists as an [[ion]] in [[chemical compound]]s. Sodium ions are found in the ocean. It is also found as sodium chloride in the earth's crust, where it is mined.<br/><br/>Sodium is normally made by [[electrolysis]] of very hot [[sodium chloride]] that was melted.<br/><br/>== Use in organisms ==<br/>Sodium ion in the form of [[sodium chloride]] is needed in the human body, but large amounts of it cause problems, which is why one should not eat too much salt and other food items with huge sodium amount (such as biscuits with [[baking soda]]). Many organisms in the ocean depend on the proper concentration of ions in sea water to live.<br/><br/>==Related pages==<br/>* [[List of common elements]]<br/>* [[Hyponatremia]] (a medical problem caused by not having enough sodium in the body)<br/><br/>== References ==<br/>reflist<br/><br/>Periodic Table<br/><br/>[[Category:Alkali metals]]<br/>[[Category:Chemical elements]]<br/><br/><br/>chem-stub<br/>
