Fluorine

Radio isotope name Fluorine-18 Name of application (the purpose to which it is applied) It is used in the radiopharmaceutical industry, positron emission tomography: metabolic abnormalities Diagram of atomic structure of this isotope Main uses of the radio isotope Fluorine-18 is the most frequently used radioisotope in Positron Emission Tomography and the radiopharmaceutical industry. “PET is imaging for cancer. Fluorine-18 is synthesised into fluorodeoxyglucose for PET.” (Wikipedia).

I purchased a gram for $5. In this experiment, I noticed that when the skin and eyes are exposed to this element, they can get very irritated. A person’s respiratory system can also get very irritated. Chlorine and fluorine also have these same physical properties as Bromine does. Bromos’ melting point is 19.04. It also has a boiling point of 137.8 and a freezing point of -7.2 degrees Celsius. In this experiment, I also discovered that Bromine cannot be sublimated because

Super fluorine symbol is F and shines the letter F up in a dark night sky where the brightest stars are. To make them pop out so everyone in the city of New York knows he is here to save them from nasty bacteria. Fluorine atomic number is the number nine. Fluorine is originally a pale yellow. He came from outer space from a low mass star’s epic death. The low mass star life cycle was to the end moreover, now it's a white dwarf. Low Mass star begin their life with a stellar nebula then an average

Preparation and Characterization of Electrospinning Fluorine-doped Tin Oxide for Solar Applications. Shaker Ebrahim, Marwa Adel a, Moataz Soliman Department of Materials Science, Institute of Graduate Studies and Research, Alexandria University, P.O Box 832, Egypt a Department of Physics, Faculty of Science, Alexandria University, Egypt Abstract Transparent conductive films of fluorine doped tin oxide (FTO) electrospun on glass substrate were prepared. These transparent conductive films were prepared

needs glasses. Rubidium is not found on its own a lot of the time, it is mainly used with other compounds and is more commonly found with other chemicals (source 11). Group 7: Fluorine everyday use When it comes to everyday use fluorine is most common in our toothpaste as a prevention of tooth decay. Dentists use fluorine as a substance straight on your teeth and in many of dental mouthwashes and as an addition - as maintenance to our bones. It has also been found in some refrigeration appliances

sense to use the electron dot structure. This one should be used because it shows the number of electrons that fluorine has, it also shows that fluorine has an unpaired electron. I know that fluorine has 7 valence electrons. Fluorine really wants to gain one more electron to become a noble gas, which means that it is willing to do just about anything to achieve that. That is why fluorine is so reactive; it will react with a lot of

overtaken in reactivity by fluorine, chlorine and bromine. Astatine Astatine is at the bottom of group 7. It is over taken by all the elements above it and is not overly reactive with water. Chemical trends in group 7 Bromine is the third element within group 7, It is also the third most reactive in the group. Bromine displaces the elements below it: Iodine and astatine on account of them not being as reactive as bromine. But it cannot displace chlorine and fluorine due to them being more reactive

two bonds of which are between carbon and carbon and between carbon and fluorine. These two bonds are both extremely stable, making it difficult to break their bonds in order to initiate a chemical reaction. The structure of the PTFE chain also plays an important role into the inertness of PTFE; the chain is a spiral shape of which tightly packs the fluorine atoms around the weaker carbon-carbon bonds. This is due to the fluorine atoms being much larger than that of the hydrogen atoms of which forces

Chlorine is a heavier and larger molecule than Fluorine. Chlorine’s atomic weight is 35.4257 Da while Fluorine’s atomic weight is 18.9984032 Da.6 When looking at atomic radii, Chlorine (79pm) is almost twice as big as Fluorine (42pm)7. These trends do not seem to apply to the alcohols however. The hydroxyl group weighs less than both Chlorine and Fluorine (17.00194 Da6). Oxygen is slightly larger than Fluorine (48pm vs 42pm)7 but is still much smaller than Chlorine (79pm)7. The
