The Element Fluorine
Fluorine is an element that appears in the periodic table. It is apart from the halogen series. It appears in group 17 and period 2. It is important to understand its structure ,physical , and chemical properties. Fluorine is the 13th most abundant element on earth and is very important to earth today. Fluorines mysterious structure reacts vigorously with itself and other elements making things that impacted our technology, history, and daily lives. Fluorine is the chemical element of atomic number 9, a poisonous pale yellow part from the halogen series. It is the most reactive element and is composed of diatomic molecule F2. Fluorine was discovered in 1886 by Joseph Henri Moissan, who also produced the first artificial diamond. The element Fluorine has nine protons and electrons and ten neutrons. Fluorines atomic mass is 188.998404 amu. Fluorines atomic number is 9. Fluorines density at 293 K is 1.696 g/cm. That makes fluorine about 1.3 times as dense as air. The electron configuration of Fluorine is [He] 2s2 2p5. Its crystal structure is cubic. To continue Fluorines name origin came from the latin word fluo (flow). Fluorine went through a long process before being discovered. Georgius Agricola german mineralogist in the 1530s described the use of the mineral fluorspar in metal refinal. “Fluor” in fluorspar is where fluorine got its name. Although Agricola didn't realize fluorspar was a mineral of Fluorine. During that time Fluorspar became an intense subject to chemist. Around the1800s chemist carried out experiments on fluorspar in attempts to isolate fluorine. However they failed to do so , instead produced what we call now hydrofluoric acid, a deadly acid. Carl Wilhelm Scheele studied and set off intense work to the acid and its composition. All chemist knew already that there had been a never before seenelement. However little did they know the element they were searching for was dangerous. In attempts to isolate fluorine led to...
