Fluorine is the most reactive element.
No, it is not. The most reactive element is would be francium. The most reactive element that can be gathered in any appreciable quantity is cesium.
Fluorine would be more reactive. Fluorine is the most reactive element.
Fluorine(F2) is the most reactive element, known to react with even Xenon, Krypton, Gold, Platinum, etc.
Chlorine is the most reactive gas element. Chlorine is in the halogen family.
If by vital you mean most reactive, then the metal francium, Fr, is the most reactive element.
I would easily say that Fluorine is the most reactive element in the world. Fluorine is the most electronegative of all elements and will react with all elements. It is so reactive that it cannot be found alone in nature.
Fluorine
Caesium is the most reactive.
The most reactive is fluorine.
Potassium is most reactive with the element Oxygen. However, it should be noted that it is most reactive with a non-element: Water.
The most reactive chemical element is fluorine. Reactivity of the elements increases as we go down and to the left on the periodic table, and it also increases as we go up and to the right on the table.
No, the opposite of that.
