|
Sodium : (noun)
1: a silvery soft waxy metallic element of the alkali metal
group; occurs abundantly in natural compounds (especially
in salt water); burns with a yellow flame and reacts
violently in water; occurs in sea water and in the
mineral halite (rock salt) [syn: Na, atomic number 11]

Sodium : \So"di*um\, n. [NL., fr.E. soda.] (Chem.)
A common metallic element of the alkali group, in nature
always occuring combined, as in common salt, in albite, etc.
It is isolated as a soft, waxy, white, unstable metal, so
readily oxidized that it combines violently with water, and
to be preserved must be kept under petroleum or some similar
liquid. Sodium is used combined in many salts, in the free
state as a reducer, and as a means of obtaining other metals
(as magnesium and aluminium) is an important commercial
product. Symbol Na (Natrium). Atomic weight 23. Specific
gravity 0.97.
Sodium amalgam, an alloy of sodium and mercury, usually
produced as a gray metallic crystalline substance, which
is used as a reducing agent, and otherwise.
Sodium bicarbonate, a white crystalline substance,
HNaCO3, with a slight alkaline taste resembling that of
sodium carbonate. It is found in many mineral springs and
also produced artificially,. It is used in cookery, in
baking powders, and as a source of carbonic acid gas
(carbon dioxide) for soda water. Called also cooking
soda, saleratus, and technically, acid sodium
carbonate, primary sodium carbonate, sodium
dicarbonate, etc.
Sodium carbonate, a white crystalline substance,
Na2CO3.10H2O, having a cooling alkaline taste, found in
the ashes of many plants, and produced artifically in
large quantities from common salt. It is used in making
soap, glass, paper, etc., and as alkaline agent in many
chemical industries. Called also sal soda, washing
soda, or soda. Cf. Sodium bicarbonate, above and
Trona.
Sodium chloride, common, or table, salt, NaCl.
Sodium hydroxide, a white opaque brittle solid, NaOH,
having a fibrous structure, produced by the action of
quicklime, or of calcium hydrate (milk of lime), on sodium
carbonate. It is a strong alkali, and is used in the
manufacture of soap, in making wood pulp for paper, etc.
Called also sodium hydrate, and caustic soda. By
extension, a solution of sodium hydroxide.

Sodium : Symbol: Na
Atomic number: 11
Atomic weight: 22.9898
Soft silvery reactive element belonging to group 1 of the periodic table
(alkali metals). It is highly reactive, oxidizing in air and reacting
violently with water, forcing it to be kept under oil. It was first
isolated by Humphrey Davy in 1807.

Sodium : Sodium: The major positive ion (cation) in fluid outside of cells. The chemical notation for sodium is Na_. When combined with chloride, the resulting substance is table salt.
Excess sodium (such as from fast food hamburger and fries) is excreted in the urine. Too much or too little sodium can cause cells to malfunction, and extremes can be fatal.
Normal blood sodium level is 135 - 145 milliEquivalents/liter (mEq/L), or in international units, 135 - 145 millimoles/liter (mmol/L).
