[ˈsoʊdiəm ]

Definition

Context #1 | Noun

chemical element

Sodium is a soft, silvery-white, highly reactive metal that belongs to the alkali metals group in the periodic table. It is represented by the symbol 'Na' and has the atomic number 11. Sodium is essential for many biological processes, including nerve transmission and muscle contraction. In its elemental form, it reacts violently with water and must be stored under oil to prevent reaction with moisture in the air.

Synonyms

N/A, natrium.

Main points about word origin

  • The word 'sodium' comes from the Latin word 'soda', which refers to a type of natural mineral water.
  • The chemical symbol for sodium is 'Na', derived from the Latin 'natrium', highlighting its historical roots.

The name 'sodium' comes from the English word 'soda' and the Latin word 'Natrium,' which refers to natron, a natural mineral containing sodium carbonate. The element itself was first isolated by the British chemist Sir Humphry Davy in 1807 through the process of electrolysis of sodium hydroxide. Since then, sodium has been recognized for its critical importance in various chemical reactions and biological functions. Sodium's reactivity and abundance in nature make it one of the most well-known and studied elements, particularly due to its role in forming compounds, including table salt (sodium chloride).
