What are the steps involve when an ionic bond formation from gaseous atom?
1.Formation of gaseous cation â It involves loss of electrons by the gaseous atoms and is an endothermic process. Energy required for this process is ionization energy. 2.Formation of gaseous anion It involves the gain of electrons by the gaseous atoms and is an exothermic process. The energy released in this process is called electron gain enthalpy. 3.Combining of oppositely charged ions to form ionic compound â It involves the formation of crystal lattice by combining oppositely charged ions.It is an exothermic process and energy released is called Lattice Enthalpy (âLH0). For the stable ionic bonding the net effect of above three processes should be exothermic i.e.
