For the formation of ionic bond, electronegativity difference should be:
Correct answer: C. More than 1.7
- A. Equal to zero
- B. Equal to 0.5
- C. More than 1.7
- D. Less than 1.7
Explanation
Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond. For the formation of an ionic bond, there should be a significant difference in electronegativity between the participating atoms. Typically, an electronegativity difference of 1.7 or greater on the Pauling scale is considered indicative of an ionic bond. In other words, if the electronegativity difference between two atoms is equal to or greater than 1.7, it suggests that one atom has a much stronger attraction for electrons than the other.

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.
