Vedclass · Answer

(B) The ionization energy $(IE)$ is the energy required to remove an electron from a neutral gaseous atom to form a cation. Lower $IE$ facilitates the formation of $A^{+}$. Electron affinity $(EA)$ is the energy released when an electron is added to a neutral gaseous atom to form an anion. Higher $EA$ facilitates the formation of $B^{-}$. Therefore,for the formation of an ionic compound $A^{+} B^{-}$,the ionization energy of $A$ should be low and the electron affinity of $B$ should be high.

An ionic compound $A^{+} B^{-}$ is most likely to be formed when
