The most electronegative element on the periodic table is:
AOxygen, since it is highly electronegative in many compounds
BChlorine, the most reactive among the halogen group elements
CFluorine, with Pauling electronegativity of 4.0 on the scale
DHydrogen, smallest atom but with strong nuclear pull
Answer & Solution
Correct answer: C. Fluorine, with Pauling electronegativity of 4.0 on the scale
Fluorine is the most electronegative element (Pauling = 4.0).
