 * We use sodium everyday. Sodium chloride is used to help flavor food in the form of table salt. Sodium is also found in sodium bicarbonate, also called baking soda. Sodium is also used in most soaps and detergents.
 * Sodium is highly reactive and may ignite on contact with water. It can even cause an explosion. The strong alkali sodium hydroxide is very corrosive and should never be touched, as it can cause severe chemical burns; neither should solutions of it.
 * Sodium gets its name from the English **soda**. In Latin it was called **natrium.**
 * Modern methods of obtaining sodium metal, are based on the process invented by Sir Humphry Davy in 1806. Basically, Davy's process consisted of the electrolysis of molten sodium hydroxide.
 * Sodium is an essential element for all animal life and for some plant species.
 * In animals, sodium ions are used in opposition to potassium ions to build up an electrostatic charge on cell membranes, allowing transmission of nerve impulses when the charge is dissipated.
 * Sodium is thus classified as a "dietary inorganic macro-mineral" for animals.
 * Sodium's relative rarity on land is due to its solubility in water, causing it to be leached into bodies of long-standing water by rainfall.
 * Such is its relatively large requirement in animals, in contrast to its relative scarcity in many inland soils, that herbivorous land animals have developed a special taste receptor for the sodium ion
 * Compared with other alkali metals, sodium is generally less reactive than potassium and more reactive than lithium
 * When sodium or its compounds are introduced into a flame, they turn the flame a bright yellow color.

Sodium is a metal, and it is reactive in which it joins to other elements in compounds. Sodium chloride has a high melting point, meaning that it should be expensive to melt it in order to carry out electrosis.  Sodium is the sixth most abundant element on earth. It comprises approximately 2.6% of the earth's crust. Sodium is mostly gotten through commercially  by the electrolysis of dry fused sodium chloride.

Soap is generally a sodium salt of fatty acids, and sodium is used in most foods. Sodium is soft enough to be cut with a knife, it is light too, also It's shiny and has a silvery sheen when it's freshly cut. The common compound to sodium is sodium chloride. And lastly, Sodium occurs in many minerals, such as cryolite, soda niter, zeolite, amphibole, and sodalite.
