Question

Why is Fluorine the most active VIIA element
​

Answer 1

Relative 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.

Answer 2

Answer:

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.

Explanation:

The thing that makes fluorine so reactive is its electronegativity. Electronegativity is the tendency of an atom to attract a shared pair of electrons. Due to this charge density fluorine has high polarizability which makes it more reactive.
