Which of the following is the second most electronegative element? — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

Electronegativity is the measure of the tendency of an atom to attract the bonding pair of electrons towards them. Fluorine (3.98) is the most electronegative element in the periodic table. And oxygen (3.44) is the second most electronegative element in the periodic table due to its small size and high effective nuclear charge.
