Explanation of Solution
Introduction:
The reactive nature of an element basically depends on the atomic radius, shielding and availability of the valence electrons.
Fluorine is the most reactive because F - F bond breaks very easily. Its dissociation energy is very low due to presence of lone pair.
Atomic number of fluorine=9
Its electronic arrangement=2,7
It requires only one electron to become stable like neon.
The reactivity of Fluorine is high. This is because the valence electrons in fluorine are nearer to the nucleus than in chlorine and others and so that it is more strongly attracted.
Conclusion:
Thus, fluorine is most reactive of all non-metals.
