Elements is most reactive
(a) Fluorine
(b) Argon
(c) Helium
(d) Radon
Answer: (a)
Explanation: Fluorine is the most reactive of the elements mentioned.
Why is fluorine such a reactive element?
Fluorine(F) is a chemical element with the atomic number 9. The electronegativity of fluorine is what makes it highly reactive. The ability of an atom to attract a shared pair of electrons is referred to as electronegativity. Fluorine is more reactive than chlorine because it has a higher electronegativity. The number of electrons in an atom’s valence shell determines its reactivity. Noble gases have a low reactivity because they exhibit complete electron shells.
