About Sodium

Sodium is one of the oldest known chemical elements since it is essential for human life. It is consumed by all of us in the form of salt we use for cooking many types of foods, but is a bit dangerous for human body in high amounts (causes high blood pressure). Sodium is a soft metal and is the 6th most common chemical element on our planet. Sodium is a reactive element, especially with water and other chemical compounds, that is why it can not be found in nature as metal. The number of common sodium compounds is quite large (with sodium chloride being the most common of those), and they are used in plenty of industries, including toothpaste production, producing soaps, foodstuffs, as well as industrial and nuclear chemistry, and many others.

Na Atomic Number

What's in a name? From the English word soda and from the Medieval Latin word sodanum, which means 'headache remedy.' Sodium's chemical symbol comes from the Latin word for sodium carbonate, natrium.

Say what? Sodium is pronounced as SO-dee-em.

History and Uses:

Although sodium is the sixth most abundant element on earth and comprises about 2.6% of the earth's crust, it is a very reactive element and is never found free in nature. Pure sodium was first isolated by Sir Humphry Davy in 1807 through the electrolysis of caustic soda (NaOH). 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.

Sodium also forms many useful compounds. Some of the most common are: table salt (NaCl), soda ash (Na2CO3), baking soda (NaHCO3), caustic soda (NaOH), Chile saltpeter (NaNO3) and borax (Na2B4O7·10H2O).
