alleryIonic bonds form most easily between elements with low ionization enthalpies and high negative:
AElectron gain enthalpy
BElectron loss enthalpy
CElectrode gain enthalpy
DElectrolyte gain enthalpy
Answer & Solution
Correct answer: A. Electron gain enthalpy
1. One partner must give up an electron cheaply.
2. The other must gain one with a large release of energy.
3. Ionic bonds form more easily between elements with low ionization enthalpies and high negative electron gain enthalpy.
4. So the answer is electron gain enthalpy.
