Answer
The energy terms involved in the formation of an ionic solid from atoms are the the electron affinity of the nonmetal atom, ionization energy of the metal atom, and the energy of the attraction of the ions forming the ionic solid.
The lower the ionization energy, the lower is the energy of the metal. but the electron affinity of the nonmetal is high, and the energy of the attraction of the ions is large.
