The influence of oxidation state on the electronegativity of tin
... The nature of the bonds between tin and its substituent is a function of both the oxidation state of the tin and the electronegativity of the second moiety. In general, the effective electronegativity of any atom increases with increasing oxidation state. Covalent character is a feature of bonds bet ...

The high reactivity of fluorine is explained partly in terms of its low bond dissociation enthalpy, which means that little energy is required to break the F-F bond in the initial stages of a reaction. Another factor is the tendency to form strong bonds with other elements. Thus, fluorine tends to b ...
