Fluorine effect elements bond energies

As with the other first-row elements, much of the chemistry of fluorine stands distinctly apart from that of its congeners. Anomalous effects are due partially to the extreme electronegativity of fluorine, partially to the inability for the fluorine octet to expand, and partially to the small size of the atom. The low F—F bond energy, coupled with the high energy of bonds formed between fluorine and other elements, makes many of the reactions of the F2 greatly exothermic, and a number take place with almost explosive violence. (Fluorination of organic compounds with undiluted fluorine, for instance, can be particularly hazardous.)...
