Verified step by step guidance1
Understand that electronegativity is the tendency of an atom to attract electrons towards itself when it forms a chemical bond.
Recall the general trend of electronegativity in the periodic table: it increases from left to right across a period and decreases from top to bottom within a group.
Identify the positions of the given atoms in the periodic table: Fluorine (F), Chlorine (Cl), Oxygen (O), and Nitrogen (N).
Compare their positions: Fluorine and Chlorine are in Group 17 (halogens), with Fluorine above Chlorine; Oxygen and Nitrogen are in Period 2, Groups 16 and 15 respectively.
Since electronegativity increases across a period and decreases down a group, Fluorine, being at the top right among these options, has the highest electronegativity.
