Which element has the highest electronegativity on the Pauling scale?
A
Cesium (Cs)
B
Chlorine (Cl)
C
Oxygen (O)
D
Fluorine (F)
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 that the Pauling scale is the most commonly used scale to quantify electronegativity values of elements.
Recognize that electronegativity generally increases across a period (left to right) on the periodic table and decreases down a group (top to bottom).
Compare the given elements: Cesium (Cs) is in Group 1 and Period 6, Chlorine (Cl) is in Group 17 and Period 3, Oxygen (O) is in Group 16 and Period 2, and Fluorine (F) is in Group 17 and Period 2.
Using the trend, identify that Fluorine (F), being in the top right corner of the periodic table (excluding noble gases), has the highest electronegativity on the Pauling scale.
