What is fluorine?
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium .
Is francium radioactive?
Francium is a highly radioactive metal that decays into astatine, radium, and radon. Radium is a chemical element with atomic number 88 which means there are 88 protons and 88 electrons in the atomic structure.
Why is fluorine so reactive?
To understand fluoride we first have to talk about fluorine. Fluorine is an element, the most electronegative element on the periodic table which makes it extremely reactive. This means it loves electrons and like all elements it wants to become stable, to do so it has to pick up one more electron.
How long does it take to make monofluoride from francium?
, Three full years of university chemistry. You’d have to work fast to form the monofluoride salt, as the most stable isotope of Francium is Fr223 has a T ½ of ~22 minutes. Thant means given a 1 gram sample of freshly prepared pure Fr223, in 22 minutes only ~½ of it will be left.
7 Pharmacology and Biochemistry 7.1 Pharmacology Considered a trace element, fluoride is any combination of elements containing the fluorine atom in the -1 oxidation state (fluoride ion). Due to its reactivity, fluorine is found in nature as fluorine compounds or fluorides.

Fluorine is a chemical element with symbol F and atomic number 9. Classified as a halogen, Fluorine is a gas at room temperature.
What is the electronegativity of fluorine?
As the most electronegative element, it is extremely reactive, as it reacts with almost all other elements, except for helium and neon. Among the elements, fluorine ranks 24th in universal abundance and 13th in terrestrial abundance. Fluorite, the primary mineral source of fluorine which gave the element its name,…
What is the atomic number of fluorine?
Why can’t we isolate the element fluorine?
The early chemists were aware that metal fluorides contained an unidentified element similar to chlorine, but they could not isolate it. (The French scientist, André Ampère coined the name fluorine in 1812.) Even the great Humphry Davy was unable to produce the element, and he became ill by trying to isolate it from hydrofluoric acid.
