Sodium monofluoride
n/a
Sodium atom is an alkali metal atom. It has a role as a Saccharomyces cerevisiae metabolite.
A member of the alkali group of metals. It has the atomic symbol Na, atomic number 11, and atomic weight 23.
It is a soft, silvery-white, highly reactive metal. Because it has a single electron in its outer shell, which it readily donates, creating a positively charged ion—the Na+ cation.
Sodium is the sixth most abundant element in the Earth’s crust and exists in numerous minerals such as feldspars, sodalite, and rock salt (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth’s minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans.
Sodium is an essential element for all animals and some plants. Sodium ions are the major cation in the extracellular fluid (ECF) and as such are the major contributor to the ECF osmotic pressure and ECF compartment volume.
Fluorine is a chemical element with the symbol F and atomic number 9.
It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive, as it reacts with almost all other elements, except for helium and neon.
Fluorocarbon gases are generally greenhouse gases with global-warming potentials 100 to 20,000 times that of carbon dioxide.
Organofluorine compounds often persist in the environment due to the strength of the carbon–fluorine bond. Fluorine has no known metabolic role in mammals; a few plants and sea sponges synthesize organofluorine poisons (most often monofluoroacetates) that help deter predation.
