Fluorine

Fluoride has been shown to be toxic and affects the brain and kidney when ingested. Research lasting one year has demonstrated that a very small quanitity of fluride added to water was suffiecient to cause changes to the kidney and brain could lead to Alzheimer’s. Fluoride allows aluminium a heavy metal to cross the blood brain barrier which can therefore cause this sickness associated with this element. Viewpoints Against The dose of fluoride is different for every person as it cannot be

Introduction The radical chlorination of chlorobutane is performed using AIBN and sulfuryl chloride. The purpose in doing this is so that the 4 different products yielded could be observed and analyzed. The four products produced are, 1,1-dichlorobutane, 1,2-dichlorobutane, 1,3-dichlorobutane, and 1,4-dichlorobutane. For each product the chlorine adds in a different location relative to the original chlorine. This is due to a number of reasons, including the degree of carbon substitution and proximity

can make informed decisions. Often times these surveys are bias to one side or the other, so I shall be giving information on both sides of the issue, the future outlook, and my personal opinion in order to help inform you to decide on your own. Fluorine is an element that reacts with minerals in the earth to create a salt. The salt is often naturally occurring in nature and is found in very small amounts in urban and rural wells. Although it is

NaBr. In reaction to AgNO3 and NH4OH, the unknown halogen has no reaction. These non-reactions eliminate NaBr as an option, so the unknown halogen must be NaF, which was later confirmed true by the teacher. In this experiment, it was concluded that fluorine, chlorine, bromine, and iodine will react similarly, but with slight variations. These results coincide with the fact that elements in the same group have similar reactions because they have the same number of valance electrons. Evaluation: EVALUATIONS

Fluoride is the ionic form of the element fluorine, different in chemical and physical properties. It is most usually used in compounds for industry, however, it can be added to water sources. Few areas in the UK have fluoridated tap water, providing them with key nutrients needed by the body and an efficient method of preventing tooth decay. On the other hand, there has been speculation linking fluoride to certain disorders and diseases which has caused concern within the country. Although Fluoridated

for sustaining life, Australia’s drinking water has been fluoridated since 1970 however there are arising concerns regarding its safety to the human health and the environment but ‘Should Australia continue using fluoridated water?’ (NHMRC 2016). Fluorine (F) is an element found in the 7th group of the periodic table from the halogen family. It’s an element that most reactive as it only needs to gain one electron to form Fluoride ion (F-). It’s in this form of fluoride that is found in our drinking

Drink 8 glasses of water a day! Everywhere you go, you see and hear this but would you if you knew what was in it? If you knew would you still drink it? Lots of chemicals are added to get water fresh and pure. You’re told they all have health benefits. But is this true? One chemical isn’t as healthy as all the rest. It’s quite harmful. This is fluoride. Fluoride shouldn’t be in our waters because fluoride in high levels can cause dental fluorosis, cavities, and decay. With fluoride in our water,

Imagine after years of being dead, a human body is found and all that is really left of them is their teeth. Why? It may be because of the way they took care of their teeth while they were alive and the precaution methods they were educated about. Educating people about oral health is really important because teeth are the strongest bone in our body and they even preserve the most after we pass away, this means it is an essential factor to knowing how to protect them from getting a disease and keeping

existed on Earth?” Therefore, the fluorine dating method was invented by the collaboration of Emile Rivière and Adolphe Carnot in the 1890s to record an accurate dating of specimen. It was later enhanced by Kenneth Oakley. The fluorine dating method measures fluoride ions that are within most soils and ground waters. Over time bones pick up on fluoride ions through ground waters or soils that are moist. The older the bones or specimen is, the higher the fluorine is.
