Web2+ charge. Explain this based on Z-effective, electron affinity, ionization energy, and/or electron configuration. When a group 1A element loses an electron, the shielding goes down. This is the basis of ionization energy, the energy needed to remove an electron in the gas phase. The higher the Z eff, the higher the ionization energy. WebNa + ( g) + Cl - ( g) NaCl ( s) Ho = -787.3 kJ/mol. The lattice energies of ionic compounds are relatively large. The lattice energy of NaCl, for example, is 787.3 kJ/mol, which is only slightly less than the energy given off when natural gas burns. The bond between ions of opposite charge is strongest when the ions are small.
