“Sodium (Na)”  [Atomic Number: 11] 

Sodium

  In chemistry, Sodium (Na) is an element in the alkali metal group of the periodic table of elements.
In elemental science, Sodium (Na), is a s-block element, located at the group 1, period 3 of the periodic table of elements.

Sodium+ (Na+) is a Major Positive Ion (Cation)

  In the body, Sodium (Na+) as a Sodium (Na) that has 11 electrons: two in its inner shell, eight in its second shell, and one in its valence shell (needing seven electrons to fill its valence shell) acts as a major positive ion (cation) in the fluid outside of cells.

Excess sodium is excreted in the urine.

Sodium Biochemically Functions

  In our body, Sodium (Na) is the dominant extracellular cation whose homeostasis is vital to the normal physiologic function of cells, yet it cannot freely cross the cell membrane. Most of the body's sodium is located in blood and in the fluid around cells. Sodium helps the body keep fluids in a normal balance and plays is important for nerve and muscle function. *

“Table Salts (Dietary Salts)”  

Dietary Sodium Chlorides (Table Salts)

  In our diet, Dietary Sodium Chloride (table salt), chemical symbol NaCl, is an ionic dietary compound composed of sodium (40%) combined with chloride (60%).
  In our body, table salts are an essential electrolyte, but excessive salt intake has deleterious effect on the body system. **
