Salt, also referred to as table salt or by its chemical formula NaCl (sodium chloride), is an ionic compound made of sodium and chloride ions. All life depends on its chemical properties to survive. It has been used by humans for thousands of years, from food preservation to seasoning.
Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide is used in soap manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals including humans. Sodium is an essential element for all
The high level of sodium in many processed foods has a major impact on the total amount consumed. [68] In the United States, 75% of the sodium eaten comes from processed and restaurant foods, 11% from cooking and table use and the rest from what is found naturally in foodstuffs. [69]

It was first identified by its characteristic emission lines in the Sun's spectrum. Lithium (Li) 3 λίθος (lithos) Greek "stone" From Greek λίθος (lithos) meaning "stone", because it was discovered from a mineral while other common alkali metals (sodium and potassium) were discovered from plant tissue.

A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life.
The sodium layer is a layer of neutral atoms of sodium within Earth's mesosphere. This layer usually lies within an altitude range of 80–105 km (50–65 mi) above sea level and has a depth of about 5 km (3.1 mi). The sodium comes from the ablation of meteors.
