To summarize: fluorine is an element; fluoride is an ion or a compound which contains the fluoride ion. Fluorine is an element. “Electron shell 009 Fluorine – no label” By Pumbaa (original work by Greg Robson) – File:Electron shell 009 Fluorine.svg, (CC BY-SA 2.0 uk) via Commons Wikimedia Fluorine is required for the preparation of uranium(VI) fluoride and subsequent separation of the 235 and 238 uranium isotopes by gaseous diffusion. In the manufacture of hydrogen fluoride (HF), powdered fluorspar is distilled with concentrated sulfuric acid in a lead or cast-iron apparatus. Fluorides are found in toothpaste and added to public drinking water in some countries. I'd like to keep this post sweet and to the point but not lacking substance so I think a good topic to discuss today is fluorine and how it relates to fluoride. It was a discovery of a South African plant in 1943 that would unlock the doors to fluoride research. Since the p sublevel should have 6 electrons to obtain Neon, noble gas electron configuration, fluorine has the ability to attract an electron. (2006) Protecting Groundwater for Health: Managing the Quality of Drinking-water Sources edited by Oliver Schmoll, Guy Howard, John Chilton and Ingrid Chorus. Fluorine was discovered as an element in other compounds in the early 1500s by the German physician Georgius Agricola. The key difference between fluorine and fluoride is that fluorine is neutral whereas fluoride is negatively charged. (2006) Water and fluorine reaction will give products as below. Fluorine is an element in the periodic table, which is denoted by F. It is a halogen (17th group) in the 2nd period of the periodic table. It combines with metals to make fluorides such as sodium fluoride and calcium fluoride, both white solids. Fluorine gas is denser than air and it can also be liquefied and solidified. The element Fluorine is a poisonous gas. It can help prevent tooth decay, which is why it's added to many brands of toothpaste and, in some areas, to the water supply through a process called fluoridation. The main ore of uranium contains uranium oxide, U 2 O 3. Madhu is a graduate in Biological Sciences with BSc (Honours) Degree and currently persuing a Masters Degree in Industrial and Environmental Chemistry. Fluorine is an element that also has to get an electron to achieve the electron configuration of the noble gas, neon. Fluoride toothpaste should not be swallowed and therefore not used for toddlers or anyone cannot sufficiently spit all of the toothpaste out. “Toothpaste” By William Warby (CC BY 2.0) via Flickr. Fluoride in Drinking-water edited by K. Bailey, J. Chilton, E. Dahi, M. Lennon, P. Jackson and J. Fawell. It usually exists as fluoride ion F- in aqueous solution; It remains in the air for long when attached to tiny particles.

How Fluoride Works to Prevent Tooth Decay. ... Once fluoride is in the water it is very hard to control and remove. What is Fluorine  The elements in the periodic table except the noble gases are not stable. Adding fluoride to the water supply reduces the … Moreover, the electron configuration of fluoride is 1s2 2s2 2p6. It is highly reactive, and this is due to its high electronegativity and weak fluorine- fluorine bond. It is the 13th most common element in the Earth’s crust. Among isotopes of fluorine, F-17 is not a stable isotope and it has a half-life of 1.8 hours. We can represent it by the symbol F-. The misspelling is common, but the "u" comes before the "o" in both. One complex way to get it out of the water is through an ion exchange. F2 is a pale yellow-greenish colour gas and it has a melting point of -219 °C and a boiling point of -188 °C. An ion exchange is when you take out dissolved ions in a substance. The most common fluorine minerals are fluorite, fluorspar and cryolite, but it is also rather widely distributed in other minerals. And because we are super dorks, we gave this extra electron that turns fluorine into fluoride a special place on our fluoride-door logo – … Fluorine interacts with boron, silicon, phosphorus, and arsenic at cold temperatures, forming the corresponding fluorides. Therefore, elements try to react with other elements to gain the noble gas electron configuration and achieve stability. It is the lightest of the halogens, a pale yellow-green, highly reactive gas that attacks all metals. Fluoride is the anion that forms when fluorine abstracts an electron from another electropositive element. Electrical Charge. 2. However, despite the prevalence of the fluoride ion, gaseous fluorine rarely, if ever, occurs naturally. Elemental fluorine does not occur naturally. Water fluoridation usually is accomplished by adding sodium fluoride (NaF), fluorosilicic acid (H 2 SiF 6 ), or sodium fluorosilicate (Na 2 SiF 6 ) to drinking water .
