Fluorine

The Power of Fluoride in Community Water Fluorine can be found on the Periodic Table as the ninth element. Fluoride is a chemical derived from the element fluorine. The chemical fluoride is defined as a compound of fluorine with another element or group, especially a salt of the anion F or an organic compound with fluorine bonded to an alkyl group. Fluoride is also the simplest anion of fluorine. Today fluoride is most widely known as being used to prevent tooth decay in the United States. The…

are molecules that are composed of two atoms of the same element. These are: hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine and iodine. For example, when we refer to iodine, in a chemical reaction, we write it down as I2, which is a diatomic molecule. The table below shows the elements and their diatomic molecule: Element Diatomic Molecule Hydrogen H2 Nitrogen N2 Oxygen O2 Fluorine F2 Chlorine Cl2 Bromine Br2 Iodine…

electronegativity. What results would you expect if fluorine water and potassium fluoride were available to test? Predict what would occur in the following mixtures. If a reaction would occur, write the names of any products formed. If no reaction, state “no reaction”. Fluorine + potassium chloride → Potassium Fluoride + Chlorine Fluorine + potassium bromide → Potassium Fluoride + Bromine Fluorine + potassium iodide → Potassium Fluorine + Iodine State at least two possible sources of…

(1+) As you go down a group, the energy decreases from the top to the bottom due to the shielding effect. When there are a lot of electrons shielding the outer electron shell from the nucleus, energy is less needed to expel an electron from an atom. Fluorine has the most ionization energy and Caesium with the least. As you go across a period, energy is increased along the periods. Ionic radius– Ionic radius is the measurement of distance between the nucleus and electron in the outer shell. When…

“Magnesium was discovered by Sir Humphrey Davy in England (1755). Sir Humphrey Davy also discovered MgO and HgO. The original name of Magnesium is Magnesia from the Greek word. In 1618, a farmer at Epsom in England gave his cows water from a well, but the cows refused to drink because of the water’s bitter taste. However, the farmer noticed the water seemed to heal scratches and rashes. The words spread out. Eventually it was recognised to be magnesium sulphate, MgSO4. Until 1755, it recognized…

Chromium reacts directly with fluorine to create chromium fluoride (CrF6). "Chromium metal reacts with the halogens fluorine, F2, chlorine, Cl2, bromine, Br2, and iodine, I2, to form the corresponding trihalides chromium(III) fluoride, CrF3, chromium(III) chloride, CrCl3, chromium(III) bromide, CrBr3, or chromium(III) iodide,…

Unknown #2, or fluorine, cannot be placed anywhere on the periodic table except at the top of group 17 primarily because it is a gas. It would not fit into unknown #4’s place either because of…

chlorine was associated with various diseases such as cancer, asthma, allergies, dysbiosis and more. Plus, the chlorine from the tap water can damage our hair and skin when we shower. On the other hand, when it comes to fluorine, people don't know too much about this byproduct. In fact, fluorine is a byproduct from our tap water. It is harmful to the germs which live in your tap water and also harmful to your body. When you drink tap water, you should know that fluoride is absorbed into your…

Fluoride, consumed in its varying forms, undergoes hydrolysis in the stomach which frees fluorine anions (F-), completely releasing them from their parent compound (Turney, et al., 2011). The fluorine anion is referred to as fluoride, the molecule of focus in this toxicological report. Fluoride readily crosses cell membranes by means of a pH gradient in which its negative charge becomes attracted to the free hydrogen cations found in acidic environments. This gradient and binding of fluoride…

Fossils are considered essential for the study of biological evolution because they are important in creating a time frame for once living organisms. They are the only specimen that provide us with direct physical evidence of the existence of past life as well as showing us the proof of evolution through the changes of each fossil’s skeletal structure. Sometimes interpreting the sequence of evolution within a living creature is difficult as the full range of fossils may not have been found,…
