Transcript of Fluorine- Science Project

Julie Bradshaw Fluorine Atomic Structure and Information Historical background and the story of discovery Fluorine was described by Georigius Agricola in 1529.
In 1813 Sir Humphrey Davy attempted extraction but it did not work.

It was first Isolated by Henri Moissan in France on June 26, 1886. He used a process using electricity to separated it out. Until then Fluorine was too dangerous to handle He made a special platinum container to hold the fluorine because all other container wouldn't had held the fluorine.

Scientists knew about Fluorine for a long time but was not isolated until 1886. Physical Properties Melting Point: -219.62°C
Boiling Point: -188.14°C
Group 17, Period 2 (Halogen)
Fluorine is a gas at room temperature. Fluorine will crystallize at low temperatures and high pressure and display "crystalline luster".
Brittleness, malleability, hardness, and ductility are not a concept that apply to gasses which Fluorine is when at room temperature.
Density: 1.696g/cm^3 Chemical Properties Fluorine is highly reactive. Uses of Fluorine Hazards of Fluorine The Impact and Significance Fluorine has on everyday life Conclusion Fluorine was the element I have done my project on. While doing this assignment I have learned tons of information I never knew about fluorine before. Some new facts I learned was that fluorine is used in SO many everyday items like the pot and pans, water, toothpaste, and etc, I never could have imagined how much fluorine helps. I also found out the fluorine is not always safe, it actually has many health risks and is affecting the ozone layer in certain ways. It was hard to believe how dangerous and react so easily think, a small amount is put into some people's water and used in toothpaste and other day-to-day items. After doing this assignment on fluorine I will always think of it different, and remember the different uses, risks, and characteristics of this element. References Expression of Ideas Main facts The End Thank- you for watching and reading my presentation on the element Fluorine! Fluorine has the symbol:F Atomic Number: 9 Atomic Mass: 18.998404 (19) Number of Neutrons: 19-9=10
Number of Protons: 9
Number of Electrons: 9 André-Marie Ampère Henri Moissan This short clip shows you how Fluorine reacts with others. The name comes from the Latin word "Fluere" meaning to flow Humphrey Davy named it. Fluorine is corrosive and pale yellow gas. Fluorine can sometimes be florescent. Toxicity: Very poisonous. Oxidation: Does not combine with oxygen at room temperature. Highly corrosive. When mixed with water it will end in explosion. Reacts with all elements except helium, neon, and argon. Heat Resistant. Flammable. Air conditioning Rocket Fuel because how reactive it is Refrigerant Enriching uranium for nuclear fuel to make electricity and nuclear weapons

Making steel and refining aluminum

Reduces tooth decay so it is used in toothpaste and city water supplies

Making Teflon. Teflon is a non-stick plastic coating used for metal pots and pans

Some medicines like Lipitor for high cholesterol and Prozac an anti-depressant have fluorine.

Light bulbs HAZARDS:Breaking down the Ozone Layer ( As see above)
CFC= ChloroFluoro Carbons found in aerosols and refrigerants.

If inhaled it will cause lungs to burn since it reacts with water. VERY dangerous if it contact with skin. Too much fluorine can cause many health risks. Benefits of Fluorine Helps with decay on teeth ( as shown below) Used in water, could make water safe while helping teeth * Has many helpful uses even while having haxards Fluorine impacts my life because.....
I use toothpaste, water, pots and pans, and many other items fluorine has a part of.
I think there are careers and will be more to come with this element. I say this because fluorine is in many items which can only mean the element is used very often. As time goes by there will most likely be more opportunities in using fluorine for everyday life. Fluorine - Element information, properties and uses | Periodic Table.

Scientists knew about fluorine for many years, since it was so hard to handle is was not isolated until 1886.
Fluorine has many uses that you maybe wouldn't expect due to the levels of harm and dangers.
Fluorine has many harmful effects but also has positive outcomes.
Fluorine is very reactive, it reacts with almost every element.
