Fluorine was discovered by Karl Scheele in 1771, recognized as a halogen in 1825, and included in Mendeleev's Periodic Table of 1869. Fluorine is so active that it existed only in compounds and all efforts to isolate the element failed. Because of its high corrosiveness/toxticity, early fluorine chemists died from fluorine poisoning and the element was dubbed "Tiger of Chemistry." Fluorine, from Latin "fleure" meaning to flow, is the 13th most abundant element in the earth's crust and the most reactive of all elements--it even forms compounds with noble gases.

Chlorine is formed by its breakdown. Fluorine is also created.

Fluorine
Fluorine is an element, s an atom of fluorine contains only one element - fluorine. However, the fluorine molecule consists of two atoms of fluorine.
Fluorine is an element and barium is also an element. There is no fluorine in barium and not barium in fluorine.
fluorine reacts with water veryviciously the chemical equation for it is fluorine + oxygen = fluorine oxide
Fluorine seems a likely answer
The valency of fluorine is -1.
The value of fluorine on the periodic table is 9. It is a highly reactive element and is commonly found in compounds rather than in its pure form in nature. It is used in a variety of applications, including in toothpaste and water fluoridation.
