Fluorine is the many reactive nonmetal due to the fact that it has the highest value of electronegativity. Reactivity the nonmetals is straight proportional come electronegativity. Having actually the electronegativity the 4, it has the highest capacity to tempt the mutual pair that electron towards itself. As its capacity to lure the shared pair the electron towards itself is more than any kind of other element, fluorine is claimed to be the many reactive nonmetal in the routine table.

This was a short and straight answer. If you desire to gain into some depth the this topic then this short article is because that you.
What is reactivity?
Let’s store things simple. Reactivity is the capacity of an element to react and type a shortcut with an additional element. The more reactive facets react conveniently without request high quantity of energy. Top top the other hand, much less reactive aspects don’t react readily with other elements. They require some energy to form bond.
Basis that reactivity:
Just like any kind of other property, reactivity also depends on an additional property. The communication of reactivity is various for metals and non metals. Because metals shed electrons, your reactivity counts on their electropositivity (ability to shed electrons). It has a direct relation v electropositivity.
But we understand that nonmetals execute not lose electrons they expropriate it. So us cannot measure their reactivity ~ above the basis of electropositivity due to the fact that their behavior is totally different indigenous metals. It’s as with comparing the capability of a bird to fly v a fish. So we have an additional term because that nonmetals and also that is “electronegativity”.
A short intro come electronegativity:
The capacity of an element to lure the shared pair of electron in the direction of itself is known as electronegativity. It’s simply an capacity so it doesn’t have any unit. The minimum worth is 0.7 assigned come Cesium metal. Maximum value is 4 assigned to fluorine. Every the other facets lie between this scale and it is known as Pauling’s scale of electronegativity.
Relation that electronegativity v reactivity:
It additionally has a direct relation. The much more electronegative nonmetals will be more reactive. An in similar way less electronegative nonmetals will show less reactivity. But, why? Let’s know it better. Reactivity is capacity of bond formation. Because that nonmetals bond is developed when they expropriate electrons from other elements. If their ability to attract the shared pair that electron is less, exactly how will they accept electrons? So because that bond development nonmetals have to accept electrons and to expropriate electrons they need to lure them for this reason they call for high electronegativity to be reactive.
Periodic tendency of electronegativity and also reactivity:
If you relocate upward to downward in any group of routine table friend will check out that electronegativity decrease down the group. While relocating left to best in any duration you will notice that electronegativity of facets is slowly increasing. Let’s currently see the tendency of reactivity for nonmetals. Together we have questioned the reactivity has actually a direct relation through electronegativity. Therefore the above trend is very same for reactivity that nonmetals. Left to appropriate it increases and also top to bottom that decreases.
Where many reactive nonmetals are found in routine table?
If we look to the tendency of reactivity that tells us that the most reactive group of nonmetals will certainly be VII A (VIII A is no reactive). As it comes in the end and also according to team trend the most reactive aspect from VII A have to be the optimal member. The very first element of VII A is Fluorine (as it is the many electronegative element of periodic table).
Reaction of Fluorine with Xenon:
Xenon (Xe) belongs to VIII A team of periodic table. VIII A elements are considered to it is in non reactive together they have actually 8 electron in their outermost shell. They follow the octet rule and are secure without creating bond with any type of element. However as over there are many exceptions in regular table, we also have one here. Xenon develops bond through Fluorine atom. Yes, friend heard it best Xenon reacts v Fluorine. The procedure of bond development is an extremely complicated. I didn’t comment on this to define the procedure but come tell you around the reactivity that Fluorine. No other facet of periodic table reacts v VIII A elements. Just fluorine has the capacity to react v Xenon.
3 varieties of fluorides are created on reaction through xenon.
Xe + F2 → XeF2
Xe + 2F2 → XeF4
Xe + 3F2 → XeF6
Reactivity is the capability of any type of element to form a bond with one more element.
It relies upon electronegativity because that nonmetals while for steels it relies on electropositivity.
Electronegativity is the capability of an aspect to lure the shared pair the electron in the direction of itself.
In regular table electronegativity and reactivity both boost left to best in a period and diminish from top to bottom in group.
VII A group is the most electronegative and reactive team of periodic table.
Fluorine is the many reactive nonmetal since it is the many electronegative nonmetal in the routine table.
It’s electronegativity is 4 (highest) on Pauling’s scale.
