Which of the following is the most electronegative?

Question

Quizplus · Accepted Answer

Electronegativity is the measure of the attraction of an atom for the electron density in a covalent bond. Fluorine has the highest electronegativity value of 4.0 among the given elements, which is due to its smaller size and higher effective nuclear charge. Oxygen has an electronegativity value of 3.5, carbon has an electronegativity of 2.5, and sodium has an electronegativity of 0.9. Therefore, option A, fluorine, is the most electronegative among the given options.
