Which element is the most electronegative of all?
AChlorine
BFluorine
CNitrogen
DOxygen
Answer & Solution
Correct answer: B. Fluorine
1. Electronegativity rises towards the upper right of the periodic table.
2. Fluorine sits at that extreme and carries the highest value of any element.
3. Oxygen, nitrogen and chlorine are all strongly electronegative but none exceeds fluorine.
4. Noble gases are left out of the comparison because they do not normally share electrons.
