Verified step by step guidance

Understand the concept of electronegativity: Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The higher the electronegativity, the stronger the pull on electrons.

Recall the trend of electronegativity in the periodic table: Electronegativity increases across a period from left to right and decreases down a group.

Identify the position of each element in the periodic table: Fluorine (F), Oxygen (O), Nitrogen (N), and Chlorine (Cl) are all in the second period, except Chlorine, which is in the third period.

Compare the electronegativity values: Fluorine is at the top right of the periodic table, making it the most electronegative element. Oxygen and Nitrogen follow, with Chlorine being less electronegative than Fluorine but more than many other elements.

Conclude that Fluorine (F) has the highest electronegativity among the given elements, as it is the most effective at attracting electrons towards itself.
