Sodium, categorised by the chemical symbol Na (from the Neo-Latin word 'natrium'), is a chemical element, with the atomic number 11. It is an alkali metal, in group 1 of the periodic table (formerly known as ‘group IA’) and is described as a soft, silvery-white, and highly reactive alkali metal. Sodium quickly oxidises in air and intensely reacts with water. Therefore, it is stored in inert mediums like kerosene to prevent unintended reactions.

More Info

Pioneered by Humphry Davy in 1807 through the electrolysis of sodium hydroxide, sodium has since become a cornerstone in various industries. From the production of sodium hydroxide for soap manufacturing to the use of sodium chloride as a de-icing agent and nutrient for both animals and humans, sodium plays a vital role in our everyday lives.

While sodium doesn't occur freely in nature, its potential is harnessed by preparing it from compounds. As the sixth most abundant element in the Earth's crust, sodium is found in diverse minerals such as feldspars, sodalite, and halite. It is present in great quantities in the earth's oceans as sodium chloride (common salt). It is also a component of many minerals, and it is an essential element for animal life. As such, it is classified as a “dietary inorganic macro-mineral.”
