Which element has the highest electronegativity in the periodic table?
AOxygen
BFluorine
CChlorine
DNitrogen
Answer & Solution
Correct answer: B. Fluorine
1. Electronegativity peaks in the top-right corner of the table.
2. Fluorine is the smallest non-metal with high nuclear charge.
3. Its tiny radius pulls bond electrons strongly.
4. So fluorine has the highest electronegativity (3.98 on Pauling scale).
5. Oxygen comes second around 3.44.
