how is fluorine obtained in its pure form
Answers
Fluorine is a chemical element that in pure form occurs as a dimer of two fluorine atoms, F 2 . The fluorine atom has the ground state electron configuration 1s 2 2s 2 2p 5 . There is only one stable, naturally occurring isotope of fluorine: 19 F. However, the radioactive isotopes 17 F, 18 F, and 20 F are known. The inclusion of the isotope18 F (half-life 110 minutes) in bioorganic molecules is an important noninvasive technique used in the study of living tissue by positron emission tomography.
Fluorine is the most electronegative element. It is the lightest and most reactive element in the halogen family. Fluorine is a poisonous, corrosive, pale yellow gas with an acrid odor. It is the most powerful oxidizing agent known. The low F–F bond energy and the high energy of bonds between fluorine and other elements combine to make reactions of fluorine exothermic.
