  Sodium - Wikipedia, the free encyclopedia
Sodium is a soft, waxy, silvery reactive metal belonging to the alkali metals that is abundant in natural compounds (especially halite).
Sodium is relatively abundant in stars and the D spectral lines of this element are among the most prominent in star light.
Sodium chloride or halite, better known as common salt, is the most common compound of sodium, but sodium occurs in many other minerals, such as amphibole, cryolite, soda niter and zeolite.

Sodium floats in water, as well as decomposing it to release hydrogen gas and hydroxide ions.
A possible explanation for the abberant behavior of sodium is that this element has one free electron that is pushed closer to the other 10 electrons when placed under pressure forcing interaction that is not normally present.
Sodium chloride, better known as common salt, is the most common compound of sodium, but sodium occurs in many other minerals, such as amphibole, cryolite, halite, soda niter, zeolite, etc. Sodium compounds are important to the chemical, glass, metal, paper, petroleum, soap, and textile industries.

In addition, to achieve this change in the movements of potassium and sodium in the kidney, the organism is obliged to hypertrophy the zona glomerulosa of the adrenal cortex in order to considerably increase the secretion of aldosterone which regulates the excretion of potassium and retention of sodium.

 The Environmental Literacy Council - Sodium
Sodium is a soft, highly reactive metal that melts at a very low temperature, lower than that of boiling water (97.5 C).
Sodium ion gradients are also responsible for various transport processes, including sugar transport in the intestine and amino acid transport in red blood cells.
Sodium is lost along with moisture when we perspire (sweat is salty), so it is important to take in salt as well as water when exerting oneself in hot weather, to avoid dehydration and maintain the correct composition of body fluids.

Soils with an excess of sodium ions, compared to calcium and magnesium ions, remain in a dispersed condition, almost impermeable to rain or irrigation water.
When the SAR test indicates an excess of sodium, the addition of gypsum to free the sodium and allow it to be leached from the soil, may be necessary.
Sodium adsorption levels of irrigation water should be less than 10, espcially if young plants are to be grown (Davidson, et al.).

 Fluoride: risks and benefits?
With a very small chance of being wrong, the study showed that sodium fluoride does cause cancer at cumulative doses comparable to those ingested by humans over a number of years.
It has been suggested that the experimental animals received abnormally high doses-so high that many common substances like sodium chloride (common salt) would show ill effects at the same dose and that in any case a person would have to drink 79 litres of water a day for life to equal the fluoride dose.
Students were invited to paint an egg with sodium fluoride (topical application) and then invited them to draw positive conclusions about water fluoridation (systemic application) for their community.
