An ionic bond around A+B- is most likely to be formed when:

Explanation

An ionic bond A+B- is most likely to be formed when the ionization energy of A is low and the electron affinity of B is high.beacause A will lose an electron and B will gain an electron, forming an ionic bond.Ionization energy is the energy required to remove an electron from an atom. A low ionization energy means that it is easy to remove an electron from an atom, which makes it more likely to form a positive ion (cation).Electron affinity is the energy released when an electron is added to an atom. A high electron affinity means that an atom is more likely to accept an electron, which makes it more likely to form a negative ion (anion).
