Question
Which element is expected to have the lowest electronegativity?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Electronegativity decreases down a group and increases across a period. Cesium (Cs) is located at the bottom left of the periodic table, far from fluorine, the most electronegative element. It has a very low electronegativity.
Hint
Think about the element farthest from fluorine in the top right corner.
