Fluorine: the essentials Fluorine: the essentials. Fluorine is a Group 17 element. Fluorine is the most electronegative and reactive of all elements. It is a pale yellow, corrosive gas, which reacts with practically all organic and inorganic substances.Finely divided metals, glass, ceramics, carbon, and even water burn in fluorine with a bright flame.luorine as fluoride (F -) is probably an essential element for humans and certainly is for some molluscs. In some areas, fluoride ion is added to drinking water (in very low concentrations) since it renders tooth enamel relatively immune to bacteriological attack.

- Hydrogen fluoride is a chemical molecule formed from the covalent bonding of hydrogen and fluorine atoms. This article discusses the many uses of hydrogen fluoride, as well as the potential dangers of exposure to this chemical.ydrogen fluoride is a molecule that is formed from combining a hydrogen atom with a fluorine atom. It is a highly valuable molecule in industry, but is also a very dangerous chemical for biological systems.

- Fluorine's special status also stems from the 'fluorine factor', the ability of this little atom to fine-tune the chemical properties of an entire molecule. For example, replacing hydrogen with fluorine can protect drugs from degradation by metabolic enzymes, extending their active lifetimes inside the body.

- The Bond Type and Structure of HF. Hydrogen fluoride is a polar covalently bonded molecule consisting of one hydrogen atom and one atom of fluorine.Hydrogen's electronegativity number is 2.1 and fluorine's is 4.0, meaning the bond is very polar and nearly ionic.Because of this, the area around the fluorine atom has a slight negative charge, while the area around the hydrogen has a slight positive one.he Bond Type and Structure of HF. Hydrogen fluoride is a polar covalently bonded molecule consisting of one hydrogen atom and one atom of fluorine.

Chlorofluorocarbon A chlorofluorocarbon (CFC) is an organic compound that contains only carbon, chlorine, and fluorine, produced as a volatile derivative of methane, ethane, and propane.They are also commonly known by the DuPont brand name Freon.The most common representative is dichlorodifluoromethane (R-12 or Freon-12).ecause CFCs contribute to ozone depletion in the upper atmosphere, the manufacture of such compounds has been phased out under the Montreal Protocol, and they are being replaced with other products such as hydrofluorocarbons (HFCs) (e.g., R-410A), hydrocarbons, and CO 2.

Molybdenum Fluoride is a mineral that occurs naturally in all water sources, even the oceans. The fluoride ion comes from the element fluorine. Fluorine, the 17th most abundant element in the earth's crust, is never encountered in its free state in nature. It exists only in combination with other elements as a fluoride compound.

- In general electronegativity is the measure of an atom's ability to attract electrons to itself in a covalent bond. Because fluorine is the most electronegative element, the electrons tend to hang out more toward the fluorine atom when fluorine is covalently bonded to other atoms.n general electronegativity is the measure of an atom's ability to attract electrons to itself in a covalent bond.

What Is the Most Reactive Element? The element fluorine belongs to the group of elements called the halogens. In general, the halogens are the most reactive nonmetals on the periodic table. For nonmetals, the trend of reactivity increases as you go up a group of elements. According to this trend, fluorine then would be the most reactive element in the group of halogens.

Hydrogen fluoride Hydrogen fluoride is a gas at room temperature. Its solution in water is known as hydrofluoric acid. Anhydrous hydrogen fluoride is the starting material for the production of most fluorine compounds.

It's Elemental Fluorine is added to city water supplies in the proportion of about one part per million to help prevent tooth decay. Sodium fluoride (NaF), stannous(II) fluoride (SnF 2) and sodium monofluorophosphate (Na 2 PO 3 F) are all fluorine compounds added to toothpaste, also to help prevent tooth decay. Hydrofluoric acid (HF) is used to etch glass, including most of the glass used in light bulbs.

Wikijunior:The Elements/Fluorine Where did its name come from? Fluorine gets its name from the Latin word fluere, which means to flow. Fluorspar ores were used as fluxes, which help ores to flow during smelting. Fluorine was later found to be a present in fluorspar.

Hydrofluoric acid From Wikipedia, the free encyclopedia. Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. It is a precursor to almost all fluorine compounds, including pharmaceuticals such as fluoxetine (Prozac), diverse materials such as PTFE (Teflon), and elemental fluorine itself.ydrogen fluoride gas is an acute poison that may immediately and permanently damage lungs and the corneas of the eyes. Aqueous hydrofluoric acid is a contact-poison with the potential for deep, initially painless burns and ensuing tissue death.

Lithium fluoride Lithium fluoride is an inorganic compound with the chemical formula LiF. It is a colorless solid, that transitions to white with decreasing crystal size.Although odorless, lithium fluoride has a bitter-saline taste. Its structure is analogous to that of sodium chloride, but it is much less soluble in water.It is mainly used as a component of molten salts. Formation of LiF releases one of the highest energy per mass of reactants, only second to that of BeO.ithium fluoride is exceptionally chemically stable and LiF/BeF 2 mixtures (FLiBe) have low melting points (360 C - 459 C) and the best neutronic properties of fluoride salt combinations appropriate for reactor use.

Kaleemuddin's Chemistry Midterm In F 2 the electrons are shared equally between the atoms, the bond is nonpolar covalent ; In HF the fluorine atom has greater electronegativity than the hydrogen atom. The sharing of electrons in HF is unequal: the fluorine atom attracts electron density away from the hydrogen (the bond is thus a polar covalent bond)

Compounds of fluorine Fluorine combines with hydrogen to make a compound (HF) called hydrogen fluoride or, especially in the context of water solutions, hydrofluoric acid. The H-F bond type is one of the few capable of hydrogen bonding (creating extra clustering associations with similar molecules).luorine's chemistry includes inorganic compounds formed with hydrogen, metals, nonmetals, and even noble gases; as well as a diverse set of organic compounds. For many elements (but not all) the highest known oxidation state can be achieved in a fluoride.

Fluorine At room temperature, fluorine is a gas of diatomic molecules, pale yellow when pure (but sometimes described as yellow-green). It has a characteristic pungent odor detectable at 20 ppb. Fluorine condenses into a bright yellow liquid at −188 °C (−306 °F), a transition temperature similar to those of oxygen and nitrogen.luorine has two solid forms, α- and β-fluorine. The latter crystallizes at −220 °C (−364 °F) and is transparent and soft, with the same disordered cubic structure of freshly crystallized solid oxygen, unlike the orthorhombic systems of other solid halogens.
