So in the given process of calcium fluoride, the one electron from the valence shell of calcium will be released making it as ions and this is termed as oxidation process. This one electron will be getting accepted by the fluorine ion and thus it will convert to ions.

A transfer of electrons occurs when fluorine and calcium react to form an ionic compound. This is because calcium is in group two and so forms ions with a two positive charge. Fluorine is in group seven so forms ions with a negative charge. The compound formed is known as a molecule.

Its low refractive index reduces the need for anti-reflection coatings. Its insolubility in water is convenient as well. Doped calcium fluoride, like natural fluorite, exhibits thermoluminescence and is used in thermoluminescent dosimeters. It forms when fluorine combines with calcium.

deposits. Fluorite, or calcium fluoride (CaF2), another simple halide, is found in limestones that have been permeated by aqueous solutions containing the fluoride anion. Noteworthy deposits of fluorite occur in Mexico; Cumberland, Eng.; and Illinois, Missouri, Kentucky, and Colorado in the United States.

Calcium fluoride (CaF2) is an insoluble ionic compound composed of Ca2+ and F− ions. It occurs naturally as the mineral “Fluorite” (also called fluorspar) and as “Blue-John”. This salt is the source of most of the world’s fluorine.

Industrial fluoride ingested from treated water enters saliva at levels too low to affect dental caries. Blood levels during lifelong consumption can harm heart, bone, brain, and even developing teeth enamel.

CaF2 is slightly basic. The reason is HF is a weak acid ( but it is very corrosive). When dissolved in water, the F- ion formed will undergoes hydrolysis reaction with water molecules forming HF and OH-. Thats why, it is basic.

Calcium fluoride (CaF2) is the primary source of fluorine worldwide. It occurs as the mineral fluorite or fluorspar.

CaF2

This ratio makes sense if you consider that two F– ions (each with a –1 charge) are needed to balance the +2 charge of each Ca2+ ion, making the net charge on the crystal zero. The formula for calcium fluoride is thus CaF2.

stannous fluoride

Stannous fluoride is the active ingredient in Crest Pro Health and Crest Gum toothpastes, and protects against plaque/ gingivitis, tooth sensitivity and cavities, making it the only fluoride source that fights all three. It also provides protection against erosion and bad breath.
