The Element Sodium

Sir Humphry Davy

"Sir Humphry Davy"

What is Sodium as on the Periodic Table? Definition of the Sodium Element
A soft, light, extremely malleable silver-white metallic element that reacts explosively with water, is naturally abundant in combined forms, especially in common salt, and is used in the production of a wide variety of industrially important compounds. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and Hydrogen. Refer to Sodium Reaction for its reaction to Water, Oxygen & Acids. The Atomic Number of this element is 11 and the Element Symbol is Na.

What is Sodium? Origin / Meaning of the name Sodium
Sodium, referred to as soda by the English, was isolated in 1807 by Sir Humphry Davy through the electrolysis of caustic soda. The symbol of the element is Na which comes for the Latin name for a common sodium compound called natrium (from the Greek 'nítron' a natural salt).

What is Sodium? Periodic Table Group and Classification of the Sodium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Sodium is classified as an "Alkali Metal" and located in Group 1 elements of the Periodic Table. An Element classified as an Alkali Metal is a very reactive metal that does not occur freely in nature. Alkali metals are soft, malleable, ductile, and are good conductors of heat and electricity. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals. For additional facts and information refer to Sodium Properties.

What is Sodium? Occurrence of the Sodium Element
Sodium makes up about 2.6% of the Earth's crust
Fourth most abundant element

Facts about the History of the Discovery of Sodium Element
Sodium was isolated in 1807 by Sir Humphry Davy through the electrolysis of caustic soda.

Sir Humphry Davy
Sir Humphry Davy (1778-1829) isolated sodium, Lithium, Potassium, barium, strontium, and Calciumby means of electrolysis. Davy also demonstrated the elementary nature of Chlorine, invented the safety lamp and discovered the stupefying effects of nitrous oxide.
