An ionic compound is most likely to be formed when:
Correct answer: B. The ionization energy of A is low but electron affinity of B is high
- A. Ionization energy of A is high but electron affinity of B is low
- B. The ionization energy of A is low but electron affinity of B is high
- C. Both ionization energy of A and electron affinity of B are high
- D. Both ionization energy of A and electron affinity of B are low
Explanation
An atom with high electron affinity means it will readily accept an electron from another atom. Hence, we can conclude that an ionic bond is most likely to be formed when the ionization energy of A is low and the electron affinity of B is high.

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.
