Sodium is an important element for life. It is an alkali metal and is located in group one, of the periodic table. This element is essential for the proper operation of the cells that make up nerves and muscles. Additionally, heating systems within nuclear energy reactors rely heavily on it, as an essential component. The term "Sodium" derives from the English word "soda," and the symbol, N, a, is an abbreviation for a typical Sodium chemical that is called Natrium. Both of these words are derived from neo-Latin.

There are many compounds of Sodium. The most common are Sodium hydroxide and Sodium chloride. The ionic form of it, is very common in the human body, and is a major contributor to the extracellular fluid. Sodium ions are necessary for the transmission of nerve impulses. The brain instructs kidneys to release more water into the bloodstream when too much Sodium is present.

Sodium is also important as a tracer element. Salt has played a prominent role in the establishment of trade routes, wars and cities. Medieval people utilized salt for everything from curing abscessed teeth and stomachaches to exchanging it for payment.

The discovery of Sodium was made by Sir Humphrey Davy, a British chemist. He uncovered the chemical properties of Sodium and discovered the process by which it is formed.

In the second half of the 1800s, scientists began to explore the composition of Sodium. Using caustic soda and three large batteries, Humphrey Davy was able to produce a pure form of this element. The molten substance, called Sodium Hydroxide, was thought to be an elementary substance at the time. The history of Sodium is quite long. The most common derivative of it was so trusted that it was even put to use in the mummification process.

Sodium is the seventh most abundant element on Earth. It is found in minerals, salts and food products. In the Earth's crust, Sodium is present in a concentration of 2,27%. It is rare for it to be found in its pure form. However, the element is found in a number of natural and artificial substances. In reality, salts are the primary source for creating Sodium and chlorine-containing chemicals. It's also found in great numbers across the seas. Sodium is found in nature in large deposits. Some of the most important sources include rock salt, and halite.

A common source of this nutrient is rock salt. It may be extracted naturally from the earth and refined into its purest form. Numerous minerals contain it.

Sodium is a delicate silvery metal that may be readily sliced. Whenever refrigerated, it becomes very fragile. It is a light and soft metallic element. Its oxidation state is +1. This metal is very reactive. It reacts violently with water, carbon dioxide and many other dry chemical agents. Many calories' worth of heat are produced by the interaction with liquid water. If these two compounds are combined in a closed space, an explosion may result.

Sodium is a metal with a low melting point. It is also a very strong base. When in contact with water, it forms Sodium hydroxide, which absorbs moisture.

Sodium has a powerful electrical conductivity. It has a low melting point of 208 Fahrenheit. This element has a body-centered cubic crystal structure. When Sodium molecule is burned in air, it releases hydrogen gas. As an added bonus, it forms a thin layer of Sodium hydroxide when exposed to humid atmosphere. Upon contact with atmospheric oxygen, the hydrogen gases contained in such layer may quickly ignite. The film can ignite at 125ºC.

As I said earlier, Sodium is an essential component for the healthy operation of the neural synapses and may be found in a wide variety of foods. It is widely used in the production of electricity, food, soaps, detergents, cosmetics, perfumes, and many other products. Sodium plays a role in many everyday products. It is a chemical compound used in flavoring, papermaking and manufacturing glass. In point of fact, the application of fusing technologies is now considered to be one of the most cutting-edge innovations in the mining business. This technology allows for the manufacture of a variety of high-tech materials from a small mound of rock. Sodium dissolves in liquid ammonia to give a deep blue color at low concentrations and a bronze color at high concentrations. This phenomenon is named: Bath of Electrons. It serves for instance, to carry out the Birch reaction which is very useful in the manufacturing of certain drugs and pharmaceutical products.

Sodium can be used to form Sodium superoxide, which is used in blackening of polytetrafluoroethylene. This metal reacts with hydrogen to form Sodium hydride. This later, is in turn used in the manufacture of Sodium borohydride. Both of them are widely implied in chemical industry in a vast number of reactions.
