The same fluorite crystals fluorescing in darkness after exposure to light. The phenomenon of fluorescence was given its name because it was first observed in fluorite. Actually, the glow does not come from fluorine but from small amounts of in the fluorite. Photo Credits: Rob Lavinsky...
Fluoride is an ionic compound derived fromfluorine, which is the single most reactive element; it is naturally found in many rocks. About 95 percent of the fluoride added to public water supplies is produced from phosphorite rock,according to the CDC. ...
Fluorine, the most reactive chemical element and the lightest member of the halogen elements. Its chemical activity can be attributed to its extreme ability to attract electrons (it is the most electronegative element) and to the small size of its atoms.
fluorine: You can tell because it ate the glass on its way out. Glass will actuallyburnin a stream of pure fluorine (video coming soon). So there may be some silicon fluoride lining the inside of the glass, but there is virtually no chance that there is any element fluorine still inside...

What is fluoride? Fluoride is a chemical compound that combines the element fluorine with another substance, usually a salt or metal. Common compounds like calcium fluoride are used in the manufacturing industry, though fluoridated water contains three compounds said to improve dental health: ...
Hydrogen is the mostabundant element. About 90% of the atoms and 75% of the element mass of the universe is hydrogen, usually in the atomic state or as plasma. Although hydrogen is the most abundantelement in the human bodyin terms of numbers of atoms of the element, it's only 3rd in...
Zirconium, with the presence of fluorine, is dissolvable in hydrochloric and sulfuric acid. According to the Pauling scale, zirconium has an electronegativity of 1.33. Among the d-block elements in the periodic table, zirconium has the 5th lowest electronegativity next to hafnium, yttrium, lanthanum...
Iodine is classified as a halogen — a subset of very chemically reactive elements (Group 17 on the periodic table) that exist in the environment as compounds rather than as pure elements. The other halogens include fluorine (F), chlorine (Cl), bromine (Br) andastatine(At). The term halo...
