What is Fluorine?-1Discovery and history of fluorine

FluorineSymbol F, atomic number 9

Fluorine is a halogen, and it is a nonmetal element.
A fluorine atom easily becomes a negative ion because its electronegativity is as high as 4.1.

Discovery of Fluorine

Even though the existence of the element fluorine was known in the 16th century, it took a long time before it was actually discovered.

* Fluorospar (or fluorite):
Fluorospar is the natural fluorochemicals calcium fluoride (CaF2). Fluorospar is a starting material for fluoric acid and fluorine. It has been a preferred flux for ore in the metallurgical industry. Fluorospar was given its name for its ability to cause minerals to flow, and became the origin of the element fluorine. The Latin word “fluo” means “flow.”
