Question

Which factor most strongly increases ionic character in a bond?

RankGuru · Accepted Answer

1. **Bond Nature**: No bond is purely ionic or purely covalent (except homonuclear diatomics like $H_2$).
2. **Electronegativity ($χ$)**: The ability of an atom to attract electrons towards itself in a bond.
3. **Electron Transfer**: If one atom is much more electronegative than the other, it effectively 'pulls' the electron pair towards its side, creating partial charges ($\delta^+, \delta^-$).
4. **Rule of Thumb**: As $\Delta χ$ increases, the displacement of electrons increases. A difference $> 1.7$ typically indicates $> 50\%$ **ionic character**.
5. **Conclusion**: **Large electronegativity difference** is the primary driver of ionicity.
