Which element has the highest electronegativity in the periodic table?

Answer and explanation

Correct answer: B. Fluorine

  1. Step 1: Electronegativity describes the tendency of an atom to attract a bonding pair of electrons.
  2. Step 2: Across a period from left to right, electronegativity increases; down a group, it decreases due to increased atomic radius and shielding.
  3. Step 3: Fluorine, positioned at Group 17, Period 2, has the highest electronegativity of all elements, with a Pauling value of approximately .
