.... so in such a way that they attain an outer shell containing eight electrons. The factors that effect the formation of ions are ionization energy, electron affinity, lattice energy. Figure 1 The transfer of electrons involved in the formation of (a) sodium chloride and (b) calcium fluoride. Each atom forms an ion with an outer shell containing eight electrons. For many elements, compounds cannot be formed by the production of ions, since the energy released in the formation of the lattice of ions would be ins ....
