Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Electronegativity is one measure of an element's ability to form chemical bonds by attracting an electron.
Fluorine is the most electronegative element. Fluorine has an electronegativity of 3.98 on the Pauling Electronegativity Scale and a valence of 1. A fluorine atom needs one electron to fill its outer electron shell and achieve stability, which is why free fluorine exists as the F− ion. Other highly electronegative elements are oxygen and chlorine.
