WebRelative reactivity. The great reactivity of fluorine largely stems from the relatively low dissociation energy, a standard measure for bond energies, of the F―F bond (37.7 kilocalories per mole) and its ability to form stable strong bonds with essentially all the other elements. Fluorine (F 2) and chlorine (Cl 2) are gases at room temperature. WebRelative reactivity.
