Fluorine

The water fluoridation controversy arises from political, economic, ethical, moral, and safety concerns regarding the fluoridation of public water supplies. The views of public health dominants on the most effective fluoride therapy for community prevention of tooth decay were very mixed; some state that water fluoridation is most effective for prevention, others see no special advantages and prefer topical utilization strategies. Those who were opposed argued that water fluoridation has no or…

Fluoridation of Drinking Water Jack Barth, AP Chemistry Water fluoridation is a common practice in many communities, both in the United States and worldwide. In 2012, 75% of American communities had access to fluoridated drinking water (Center for Disease Control and Prevention, 2015). The CDC also touts the many advantages of fluoridated drinking water, such as lowered tooth decay among families and fewer dollars spent on dental procedures. However, many individuals and medical institutions…

Should water fluoridation be implemented internationally? Water fluoridation refers to the controlled addition of fluoride to a public water supply to reduce tooth decay, usually accomplished by adding sodium fluoride, fluorosilicic acid or sodium fluorosilicate to water of which fluorosilicic acid is the most common. Fluoride helps to protect our teeth by a variety of ways such as altering the structure of developing enamel and encouraging remineralisation ensuring that the enamel crystals are…

Fluorine isn't simply an “F” on the periodic table. It is much more. In fact, fluorine is the most important element of any element on the periodic table. It indeed does not belong to the great collection of Noble Gases in Group 8A of the periodic table, but its position in Group 7A alongside the elegant Noble Gases solidifies it as one of the leading significant elements at our disposal. For that reason, in the the showmanship of element practicality, fluorine is an outstanding competitor! It…

vegetables. Foods cooked with fluoridated water, such as rice, pasta, steamed vegetables, etc. Non organic poultry like chicken nuggets, chicken soup, ground chicken etc. Beverages with Fluoride Fluoride has been known to be associated with have radiation development in the water supply. (Bukro, C., 1975).Fluoridated water is a known beverage to contain fluoride, but there are other drinks that contain just as must fluoride. Most beverages are also made of water which would make sense to why it…

For the water quality characteristic I have chosen fluoride. Here in Vancouver, WA the water is fluoridated using sodium fluoride of about 0.6-0.8 milligrams per liter. Most water supplies contain naturally occurring fluoride and many communities add fluoride to water. The decision for fluoride to be added to Vancouver's drinking water occurred in 1962 and ever since then has been fluoridated in compliance with Vancouver Municipal Code and EPA standards. Fluoride is an important characteristic…

2.2.2) 15 N 7 2.2.3) Fluorine has 9 electrons. It only needs one more electron to fill its outer shell. 2.2.4) If elements are in the same row they will all have the same number of electron shells. If they are in the same column they will have the same number of electrons on…

questions that have been raised according to having fluorine added to our water and what form fluorine is in when added to the water as well as what is the concentration that is typically used in drinking water. There has been a lot of debate when it comes to adding fluorine to our drinking water. This is a serious matter that I think is worth knowing about since it’s something each and every one of us consume every day. Many of the pros to having fluorine added to the public…

Magnesium Bromide and Nitrogen Trifluoride The two compounds I will be evaluating are Magnesium Bromide and Nitrogen Trifluoride. Magnesium Bromide is an Ionic compound, usually found in sedatives. While Nitrogen Trifluoride is a molecular compound, often used my industrial companies to clean a variety of equipment due to its room temperature stability and easy and safe to use form. These compounds’ lewis structures are in figure 1. Drawing lewis structures for compounds are a great way of…

elements in the group. Also, the other elements have negative melting points and poor conductivity, the same as Fluorine. “The halogens have a wide range of physical properties” (127). In addition, we observed that “Fluorine and chlorine are gases” (127). Fluorine could not be placed in group 18 as elements of group 18 are radioactive and are colorless, which do not apply to Fluorine. Another element correctly placed was, unknown #5, Gold. Gold was placed in group 11 because we observed its…
