List the relationship of electronegativity difference to the formation of an ionic bond, polar covalent bond, and a nonpolar covalent bond.
Accepted Answer
Electronegativity Difference and Bond Type
Ionic Bond:
- Large electronegativity difference (>1.7)
- Complete transfer of electrons from the metal to the nonmetal
- Electrostatic attraction between positively charged metal ion and negatively charged nonmetal ion
Polar Covalent Bond:
- Moderate electronegativity difference (0.4-1.7)
- Partial transfer of electrons toward the more electronegative atom
- Partial positive and negative charges
Nonpolar Covalent Bond:
- Small or no electronegativity difference (- Equal sharing of electrons
- No significant charge separation
