Chemical Formula. These carbon–fluorine bonds are exceptionally strong; due to the high electronegativity of the fluorine atoms (they attract the electrons in the bond strongly), the carbon and fluorine atoms end up with partial charges, which attract each other and strengthen the bond further. Chemical bonds: This pictures shows examples of chemical bonding using Lewis dot notation. A molecule of sulfur is composed of eight sulfur atoms and is therefore written as S 8. Ozone-depleting substances (ODS) contain various combinations of the chemical elements chlorine, fluorine, bromine, carbon, and hydrogen and are often described by the general term halocarbons.
