  2. Fluorine compounds - Wikipedia

    en.wikipedia.org/wiki/Fluorine_compounds

    Fluorine's chemistry is dominated by its strong tendency to gain an electron. It is the most electronegative element and elemental fluorine is a strong oxidant. The removal of an electron from a fluorine atom requires so much energy that no known reagents are known to oxidize fluorine to any positive oxidation state. [20]

  3. Fluorine - Wikipedia

    en.wikipedia.org/wiki/Fluorine

    Fluorine is a chemical element; it has symbol F and atomic number 9. It is the lightest halogen [note 1] and exists at standard conditions as pale yellow diatomic gas. Fluorine is extremely reactive as it reacts with all other elements except for the light inert gases. It is highly toxic.

  4. Properties of nonmetals (and metalloids) by group - Wikipedia

    en.wikipedia.org/wiki/Properties_of_nonmetals...

    Fluorine is an insulator in all of its forms. It has a high ionisation energy (1681 kJ/mol), high electron affinity (328 kJ/mol), and high electronegativity (3.98). Fluorine is a powerful oxidising agent (F 2 + 2e → 2HF = 2.87 V at pH 0); "even water, in the form of steam, will catch fire in an atmosphere of fluorine". [9]

  5. Ionic bonding - Wikipedia

    en.wikipedia.org/wiki/Ionic_bonding

    Pauling estimated that an electronegativity difference of 1.7 (on the Pauling scale) corresponds to 50% ionic character, so that a difference greater than 1.7 corresponds to a bond which is predominantly ionic. [10] Ionic character in covalent bonds can be directly measured for atoms having quadrupolar nuclei (2 H, 14 N, 81,79 Br, 35,37 Cl or ...

  6. Fluorine cycle - Wikipedia

    en.wikipedia.org/wiki/Fluorine_cycle

    Fluorine is the thirteenth most abundant element on Earth and the 24th most abundant element in the universe. It is the most electronegative element and it is highly reactive. Thus, it is rarely found in its elemental state, although elemental fluorine has been identified in certain geochemical contexts. [3]

    "Clean, Clean" is a song composed by Trevor Horn, Geoff Downes and Bruce Woolley. It was recorded first by the latter for his band Bruce Woolley and the Camera Club in 1979, and later by the former two as the Buggles for their debut album The Age of Plastic. It was released as the album's third single on 24 March 1980. [1]
