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: Fluorine (F), Oxygen (O), Chlorine (Cl), and Nitrogen (N).
Compare their positions: Fluorine is in period 2, group 17; Oxygen is in period 2, group 16; Nitrogen is in period 2, group 15; Chlorine is in period 3, group 17.
Using the trend, determine that Fluorine, being the most to the right and highest up among these elements, has the highest electronegativity.
