Sodium fluoride (NaF) is an inorganic compound with the formula Na F.It is a colorless or white solid that is readily soluble in water. It is used in trace amounts in the fluoridation of drinking water to prevent tooth decay, and in toothpastes and topical pharmaceuticals for the same purpose.
Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity.

[53] [54] [55] A case of a fatal poisoning of an adult with 4 grams of sodium fluoride is documented, [56] and a dose of 120 g sodium fluoride has been survived. [57] For sodium fluorosilicate (Na 2 SiF 6), the median lethal dose (LD 50) orally in rats is 125 mg/kg, corresponding to 12.5 g for a 100 kg adult. [58]

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The pnictogens [1] (/ ˈ p n ɪ k t ə dʒ ə n / or / ˈ n ɪ k t ə dʒ ə n /; from Ancient Greek: πνῑ́γω "to choke" and -gen, "generator") are the chemical elements in group 15 of the periodic table. This group is also known as the nitrogen group or nitrogen family.
Sodium fluorosilicate is used in some countries as additives for water fluoridation, opal glass raw material, ore refining, or other fluoride chemical (like sodium fluoride, magnesium silicofluoride, cryolite, aluminum fluoride) production. [5] It also is an ingredient in some ceramic cements.
