Final answer:
Fluorine does not have multiple common isotopes; its predominant and only stable isotope is fluorine-19. Unlike some other elements, fluorine has a very simplified isotopic presence on the periodic table.
Step-by-step explanation:
Regarding whether Fluorine has common isotopes, the accurate information indicates that fluorine does not have multiple common isotopes. Fluorine has an atomic number of 9, making its most prevalent isotope fluorine-19, which contains 10 neutrons in addition to the 9 protons found in the nucleus of a neutral fluorine atom. Fluorine-19 is the only stable isotope of fluorine, and unlike other elements such as carbon or tin, it does not have several stable isotopes. Additionally, fluorine's valence shell contains seven electrons, which make it highly electronegative and reactive, often leading to the formation of fluoride ions, denoted as F-.
