Which of the following has the highest value of electronegativity?
Correct answer: D. F
- A. I
- B. Br
- C. Cl
- D. F
Explanation
Elements from the halogen group including F, Cl, Br have pretty high electronegativities. The most electronegative element is Fluorine with a score of 4.0 (the highest possible.) Across from Fluorine we also have N and O with high electronegativities. Electronegativity is basically how much the elements 'want' the electrons. A simple way to think about it is that the closer an element is to Fluorine, the higher its electronegativity. The correct order of electronegativity in Halogen group is: F>Cl>Br>I.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
