- English Word Fluohydric Definition See Hydrofluoric.
- English Word Fluophosphate Definition A double salt of fluoric and phosphoric acids.
- English Word Fluor Definition A fluid state.
- English Word Fluor Definition Menstrual flux; catamenia; menses.
- English Word Fluor Definition See Fluorite.

- English Word Fluoranthene Definition A white crystalline hydrocarbon C/H/, of a complex structure, found as one ingrdient of the higher boiling portion of coal tar.
- English Word Fluorated Definition Combined with fluorine; subjected to the action of fluoride.
- English Word Fluorene Definition A colorless, crystalline hydrocarbon, C13H10 having a beautiful violet fluorescence; whence its name. It occurs in the higher boiling products of coal tar, and is obtained artificially.
- English Word Fluorescein Definition A yellowish red, crystalline substance, C20H12O5, produced by heating together phthalic anhydride and resorcin; -- so called, from the very brilliant yellowish green fluorescence of its alkaline solutions. It has acid properties, and its salts of the alkalies are known to the trade under the name of uranin.
- English Word Fluorescence Definition That property which some transparent bodies have of producing at their surface, or within their substance, light different in color from the mass of the material, as when green crystals of fluor spar afford blue reflections. It is due not to the difference in the color of a distinct surface layer, but to the power which the substance has of modifying the light incident upon it. The light emitted by fluorescent substances is in general of lower refrangibility than the incident light.
- English Word Fluorescent Definition Having the property of fluorescence.
- English Word Fluorescin Definition A colorless, amorphous substance which is produced by the reduction of fluorescein, and from which the latter may be formed by oxidation.

- English Word Fluoride Definition A binary compound of fluorine with another element or radical.
- English Word Fluorine Definition A non-metallic, gaseous element, strongly acid or negative, or 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. If set free it immediately attacks the containing material, so that it was not isolated until 1886. It is a pungent, corrosive, colorless gas. Symbol F. Atomic weight 19.
- English Word Fluorite Definition Calcium fluoride, a mineral of many different colors, white, yellow, purple, green, red, etc., often very beautiful, crystallizing commonly in cubes with perfect octahedral cleavage; also massive. It is used as a flux. Some varieties are used for ornamental vessels. Also called fluor spar, or simply fluor.
- English Word Fluoroid Definition A tetrahexahedron; -- so called because it is a common form of fluorite.
- English Word Fluoroscope Definition An instrument for observing or exhibiting fluorescence.
- English Word Fluorous Definition Pertaining to fluor.

- English Word Fluosilicic Definition Composed of, or derived from, silicon and fluorine.
- English Word Flurried Definition Agitated; excited.
