An ionic compound A+B- is most likely to form when:
Correct answer: B. Ionization energy of A is low and electron affinity of B is high
- A. Ionization energy of A is high and electron affinity of B is low
- B. Ionization energy of A is low and electron affinity of B is high
- C. Both the ionization energy and the electron affinity of A and B are high
- D. Both the ionization energy and the electron affinity of A and B are low
Explanation
Ionic compound is formed between the two atoms when one of them has low ionization energy so it can easily give away electrons and other has high electron affinity so it can easily accept electrons.

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.
