Verified step by step guidance1
Understand that electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
Recall the general trend of electronegativity on 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 elements on the periodic table: Nitrogen (N), Oxygen (O), Fluorine (F), and Chlorine (Cl).
Compare their positions: Fluorine is located at the top right of the periodic table (excluding noble gases), which typically corresponds to the highest electronegativity.
Conclude that Fluorine (F) has the highest electronegativity among the given elements based on its position and the periodic trend.
