Fluorine vs. Fluoride

Fluorinenoun

(uncountable) The chemical element (symbol F) with an atomic number of 9. It is the lightest of the halogens, a pale yellow-green, highly reactive gas that attacks all metals.

Fluorinenoun

A single atom of this element.

Fluorinenoun

A non-metallic, gaseous element of atomic number 9, strongly acid or negative, and associated with chlorine, bromine, and iodine, in the halogen group of which it is the first member. It always occurs combined, is very active chemically, and possesses such an avidity for most elements, and silicon especially, that it can neither be prepared nor kept in glass vessels, but may be contained in lead vessels. If set free it immediately attacks a containing glass vessel, so that it was not isolated until 1886. It is a pungent, corrosive, colorless gas. Symbol F. Atomic weight 19.00.

Fluorinenoun

a nonmetallic univalent element belonging to the halogens; usually a yellow irritating toxic flammable gas; a powerful oxidizing agent; recovered from fluorite or cryolite or fluorapatite

Fluorine

Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas.

Fluoridenoun

(chemistry) Any salt of hydrofluoric acid; for example, potassium fluoride.

Fluoridenoun

(chemistry) A binary compound of fluorine and another element or radical.

Fluoridenoun

A binary compound of fluorine with another element or radical.

Fluoridenoun

a salt of hydrofluoric acid

Fluoridenoun

a compound of fluorine with another element or group, especially salt of the anion F⁻ or an organic compound with fluorine bonded to an alkyl group.

Fluoridenoun

sodium fluoride or another fluorine-containing salt added to water supplies or toothpaste in order to reduce tooth decay.

Fluoride

Fluoride () is an inorganic, monatomic anion of fluorine, with the chemical formula F− (also written [F]−), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless.
