Fluorine compounds

<p><a href="/facts/Fluorine/YUV0Fb8m">Fluorine</a> forms a great variety of chemical compounds, within which it always adopts an <a href="/facts/Oxidation_state/W53W6s6V">oxidation state</a> of −1. With other atoms, fluorine forms either polar covalent bonds or ionic bonds. Most frequently, covalent bonds involving fluorine atoms are <a href="/facts/Single_bond/8qz02fEl">single bonds</a>, although at least two examples of a higher order bond exist. Fluoride may act as a <a href="/facts/Bridging_ligand/E4ytba8I">bridging ligand</a> between two metals in some complex molecules. Molecules containing fluorine may also exhibit <a href="/facts/Hydrogen_bonding/85V86IIg">hydrogen bonding</a> (a weaker bridging link to certain nonmetals). Fluorine's chemistry includes inorganic compounds formed with hydrogen, metals, nonmetals, and even noble gases; as well as a diverse set of organic compounds.
For many elements (but not all) the highest known oxidation state can be achieved in a fluoride.  For some elements this is achieved exclusively in a fluoride, for others exclusively in an oxide; and for still others (elements in certain groups) the highest oxidation states of oxides and fluorides are always equal.
