Introduction & daily life applications of halogens

INTRODUCTION: * Table salt, bleach, fluoride in toothpaste, chlorine in swimming pools—what do all of these have in common? * Add halogen lamps to the list, and the answer becomes more clear: all involve one or more of the halogens, which form Group 7 of the periodic table of elements. * Known collectively by a term derived from a Greek word meaning "salt-producing," the halogen family consists of five elements: * Fluorine * Chlorine * Bromine * Iodine * Astatine

* The first four of these are widely used, often in combination. * The last, on the other hand, is a highly radioactive and extremely rare substance. * The applications of halogens are many and varied, including some that are dangerous, controversial, and deadly.

DAILY LIFE APPLICATIONS:
FLUORINE
Introduction: Fluorine has the distinction of being the most reactive of all the elements, with the highest electronegativity value on the periodic table. Because of this, it proved extremely difficult to isolate. Davy first identified it as an element, but was poisoned while trying unsuccessfully to decompose hydrogen fluoride. Two other chemists were also later poisoned in similar attempts, and one of them died as a result.
French chemist Edmond Fremy (1814-1894) very nearly succeeded in isolating fluorine, and though he failed to do so, he inspired his

    The fluoride levels are deadly at their limits in city water. For example, “"Everything causes cancer?" by Dr. Dean Burk, chief chemist for the U.S. National Cancer Institute, answers this question with "perhaps...but fluoride causes more human cancer death, and causes it faster than any other chemical"(Roberts). Fluoride is an organic compound with fluorine bonded to an alkyl group. It was used in large doses in water at some of Hitler’s Nazi run Concentration Camps, which was to make the Jew’s more acquiescent and easier to control. The reasoning behind this is because fluoride alters the human brain, making it harder to think clearly. Although city tap water uses low quantities of fluoride, it has the same effect just at a much lower degree. It will hurt the human brain though over time, using the analogy of an overweight person that might not ever have many bad symptoms in their health for years. But In the end, they will reap what they have sown. “Studies done by Russel (1953) and Englander (1962) showed the benefits persisted and were apparent in all teeth throughout life. More recently, Stamm (1980) found that adults in a fluoridated area had fewer root caries than adults in non-fluoridated areas. Fluoridation is likely to be a powerful influence in its control” (Shek). True, fluoride may be good for the teeth, but it does more harm than good in the rest of a person’s body. Fluoride surprisingly has affected many more people’s judgments than supposed. People in the world working today in the large cities have deranged judgment concerning how much pollution is being put into the…

    The definition of reactivity as pertained to chemistry states, “The relative capacity of an atom, molecule, or radical to undergo a chemical reaction with another atom, molecule, or compound” (Reactivity, 2014). The reactivity of some elements or gases is greater than that of others. When Dmitri Mendeleev created the periodic table he arranged the elements based on their relative atomic mass. Alkali metals are very reactive when mixed with other elements and are placed in Group 1A of the periodic table. There are also extremely reactive nonmetal elements called halogens and are known to be in group 7A in the periodic table. Both the alkali metals and the halogens (nonmetals) on considered to be main group elements. When the number of outer shell electrons is closer to one or seven the higher the elements reactivity. Alkali metals contain a single electron in their outer shell which makes them highly reactive and halogens contain only seven electrons in their outer shell. Noble gases, such as helium, are not reactive because they are chemically stable and will not combine with other elements.…

    Moissan discovered fluorine in 1886. It is a chemical element with the symbol F, atomic number 9, 9 electrons and protons, 10 neutrons, and the atomic mass of 19. Being the lightest halogen, it has one stable isotope, fluorine19. At standard pressure and temperature, the element is a pale yellow gas as a liquid its a bright yellow. The electrons are located outside the nucleus of the atom. Electrons are organized in such a way that the space between them are inter dispersed. Within this space are distinct distances up to 100,00 times away from the nucleus of the atom. Reactions with fluorine are often sudden or explosive. Many substances are generally regarded as unreactive such as powdered steel, glass fragments, and asbestos fibers. Asbestos fibers are readily consumed by cold fluorine gas. Wood and even water will burn with flames when subjected to a jet of fluorine, without the need for a spark. Fluorine will melt at -219.6 C and boil at -188 C. 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 (SnF2) and sodium mono fluorophosphates (Na2PO3F) all fluorine compounds added to toothpaste, also to help prevent tooth decay. Fluorine is found in nature in the form of calcium fluoride, called fluorite, which forms regular crystals. California has many fluorite deposits. There are also deposits in Alaska and Argentina Fluorine is the most electronegative and reactive of all elements. Until World War II, there was no commercial production of elemental fluorine. The nuclear bomb project and nuclear energy. Applications, however, made it necessary to produce large quantities. Fluorine and its compounds are used in producing uranium (from the hexafluoride) and more than 100 commercial fluorochemicals, including many high-temperature plastics. Hydrofluoric acid is used to etch light bulbs and other glass. Fluorochlorohydrocarbons are extensively…
