 * Quick Facts:**
 * Fluorine has the atomic number of nine. It has nine protons, nine electrons, and ten neutrons.
 * It's average atomic mass number is 18.9984032. That means that it's mass number is 19.
 * Fluorine has a melting point of 53.5 Kelvin and a boiling point of 85 Kelvin.
 * Fluorine is classified as a nonmetal and is a gas at room temperature.
 * It's color is a pale yellow at room temperature.
 * Fluorine is the most reactive of all the elements. This makes it very hard to transport and to store.
 * Fluorine is a member of the Halogens in group 7A and in period 2.
 * Fluorine has 16 isotopes, 13 of which are radioactive.


 * History:**
 * Fluorine was supposedly discovered around the year of 1670 by a group of chemists, using fluorspar (a mineral consisting of calcium floride in crystalline form), that were trying etch glass.
 * Ferdinand Frederic Henri Moissan was the first person to isolate and produce Fluorine in 1886. He is the official discoverer of the element.


 * Where is it found?**
 * Fluorine is far too reactive to be found as a natural element. So, it is found in various compounds within minerals such as cryolite and fluorspar.
 * It was first found when a group of men found fluorspar in a cave in Russia.
 * It is very rare to find pure fluorine. So, most fluorine elements are found in fluorspar, which is much more common.


 * What are it's modern day uses?**
 * Fluorine is used industrially to purify uranium for nuclear power stations.
 * Fluorine is also used in toothpaste to prevent tooth decay (Sodium Fluoride). Toothpaste costs about $4 for 6 ounces.
 * The plastic on the nonstick surface of many pans contains fluorine.
 * Fluorine can also be found in lightbulbs and computer chips. Light bulbs cost about $5 for a box of four lightbulbs.
 * Interesting Fact about Henri Moisson**
 * He is considered the man who discovered fluorine and won the Nobel Prize in 1906 for his actions.
